Let's begin with our first class that is called join before starting or riveting. Let us see what is the theory behind the revolt join or revolt join is one rotate, gentle join, and it is an element of five degree of freedom and allows only the one rotation is used when a one part must rotate with respect to another, or linear axis, the common pair and the boat part. A good example is a ball bearing rotating over the shaft. Let's begin software just click on Start and there you find digital mock up index de m, you can emetics click on D any time it takes. Afterwards, this interface will come. And then you have to click on Insert.

If you are drawn to have first of all parts click on existing component if you are drawing with me click on new part. And then after click one time on product, if you're doing an existing component also just click one time on product and the component will dump here. If you're doing with me just click Part One click on this product the part will gender just no plus and plus and double click on this platform the drawing just double clicking and click on this x y plane and sketch option. Making a circle taking a circle from origin and diameter I'm giving 100 diameter under diameter. Then I'll start taking up difference or angle for making it symmetric, just click on control button can press control and click these two. And lastly place this edge option with this edge option at last and click on this first constant definition click on symmetric now that we get symmetric.

Now click on this question which is used for the dimension. I'm giving this as 20 degree. So 20 and afterwards, distance from air v to diss me It's 125 after work take this unwanted parts, just trimming it and one more circle click this circle click at center and constraint dimension it's, I'm giving 20 click OK. Then exit. I'm getting back now during mirror direction. And this one I'm keeping 10 Okay, this is my part one, I'm growing enough pipe to just double click on product. Now just double click on product, click on Insert, click on new pipe and one time click on product.

Afterward this dialog box will come click yes if that dialogue was done can just click on one time on product and afterward that dialog box will come just click Yes. And now similarly that process only click on this part this plus and double click on this part to now click on sketch and click on xy plane. Now, just click this outer circle and click Conduct project query element, or you can draw the circle Also, I'm clicking now the circle and it cannot get changed to now click on exit workbench. Now use pad. I'm giving this length as 200 and meter direction. Click on OK button.

Now my bikes are ready. Now I'm changing the color of this part. Just click here and click on property or shortcut is alt plus enter. You're in production, you can change this part number one that is a bracket in bracket there you find a part 1.1 you can change by dragging it out of accessing and you're also you can change in description you can write about that part and that will show in a bill of material and the final where you find the bill of material and there there's something about that Much will allow that part you are going to discuss you will find them and afterwards and now I'm giving the color for giving the color click on the graphics and no color and giving this red and transparency why expensive because it looks like a glass color. Click Apply okay I'm given the transparency that why this color has been changed for this cratic color and clicking the part two.

And again you can click just press ALT enter it will come or shortcut and for the long, long way just right click and property now no color I'm changing it to hello and during today's conference It is also click on Apply click on OK. Now my parts are ready. But like digging inside that feature doesn't come for that going back again with double click on product. Know that option get unlocked now All fly joints royalty control join. Let's see what is a new mechanism? Let's see what is the mechanism specific which a mechanism you want to apply to other choice have option to create a mechanism by clicking the new mechanism button. And you may can be changed your mechanism name by dragging it.

And you can see whatever you name want, you can type there. Then after let's click on new mechanism, you can change the mechanism name. I'm giving the up and down motion, up and down motion and the my mechanism name is up and down motion. And let's see what is the joint name Let's see what is joint name, a specific or name for the join. And other than the standard cat your name, which is in the field of highlight the text and type over the name. If we want to choose and change it.

Yeah, by dragging it, you can change this drag. join him. Suppose, join him his reward, you can click as a reward, you can take as revalued. You may change according to you, what is your requirement, what name you want to give? Now let's see what is line one and line two. Let's see what is line one and line two.

The definition of one axis on each of the two parts and are on which the mechanism can rotate. The two parts must be coincide at a colinear location. afterwards. Now for the selecting the line one, just come near to this circle, circle cylindrical surface, and you will find that dotted line. You find this dotted line which is in yellow color, just click on it, that color get changed to orange. Now, it's telling us to select the line to come automatically just click on this outer circles and when you click on this rectangle, there is a no line really you will find c applicant on line the line is coming.

But on this surface you will not find because it's not a medical or spirit type circle. If it pickier on the surface or cooler. It will find on one more on the inside. If you doesn't find at the instant, you can hide this object. And afterwards you can find this line for unhiding just right click and so now let's see what is obtained when I'm playing to let us know See what is played one ad plane to define the one plane on each part that the lock the part in the direction along the rotational axis, they must be perpendicular to the axis and coincide offset relation is established between the plane. Afterwards, just click on this plane, click here.

That's my one plane and plane two. Let's see what is null offset. Let us see what is null offset. choose this option if there is a null or zero offset between the two locations that is the plain one and this is a plain two and to align the part in this condition, I'm not Getting the null offset because I want this spot at the center if I do the null offset, it will directly stickier that is the surface a circular will stick this center directly to go upward, but I doesn't want an icon I want a certain distance that certain distance will calculate automatically. Let's see what is the offset Now, let us see what is offset. Offset choose this option if there is an offset value, the location between the plane one and plane two to align the offset by the sun between from the top deck surface that one that is a look from year to year.

It is minus 190 mm. That is the downward side. Just click on this. Let's see what is plane three and plane four. Let us see what is plane three and plane for the plane three and plane four are The field are available only by selecting the center but 10 feet below and let's see what is the center let us see what is the center or activate this oxygen allowed to define the plane three ad plane for these are the use to block the translation, degree of freedom and normal to the axis by by centering the pod and specify the plane on each part. Let's see what is the angle driven.

Let us see what is the angle driven that define angle combined to be used for the rotational and the moment is driven within the mechanism In this condition I'm giving the angled one click on OK. Now my parts are ready for the simulation but because of there are the new fixed part this is a simple fix, but let's see what is mean by fixed part. Let us see what is a fixed part of fix that is the anchor symbol, the location in a space of a part in the assembly choose this option one apart is a kinematic and must be fixed before the simulation is possible. It is the location on a you can imitate that toolbar icon I will show there. The please note that the mechanism need to exist before a part can be defined. Now I'm clicking on new fixed pipe. It is saying that the minute mechanism is up and down motion which I want from Fixed, it's asking and taking on this render the split.

Now dusting that mechanism can be simulated. After coming the dialog box, you can select your dis object, your product to the simulation form that product part from the 3d model to the mechanical motion model is click on OK. Now click on Insert, click on this simulation. Yeah, you will find this option. Let's say about this option what is the choice and the position on end what is meant by that? Let's see here. Let's see what is mean by the key position on exit.

Remember the current position of your mechanism when you are exist. The mechanism simulation if option is not activated, the mechanism can be We'll return its origin position when you exit it. So we need to keep the polish on on exit. Let's see what is a check joint limit. When activated this option open a dialog box that check to see if the joint is limited or being to check recheck throughout this simulation. Now you're indeed 3d printer, you'll find three different values that the low value that is minus 360 minus 360.

It's mean that the clockwise it will rotate 360 and after that, high value at this 360, it will rotate anti clockwise, again backward and the spin box increase by one by five increase by five. That is the frame rate in a video recording we record at 330 per second. Similarly, you're also in the spin box increased by five minutes rotational speed will be the fly at this product. Just don't change it. If you want to make a further conditions or you want your requirement you can change it. I'm not changing here, just click OK. And this object will rotate like this.

By clicking on existing position we have started at what is meant by taking keeping the position unexist. Now, just click on this insert option. And now the insert option will unlock everything. Let's see what is this option? What is this box, simulation player and commands. This symbol showed a jump to start or return instantaneously To the beginning position of the simulation regardless of the current location.

This symbols show the step backward. The step backward one frame at a time. This symbol show, play backward. Play the simulation in and reverse from the current step until it reached the beginning this symbol show, pause the simulation this symbol show play forward that played the simulation forward from the current step. This symbol show the step forward a step forward to the simulation and the one frame per play. This symbol also jumped to the end, the escape die instantaneously to the end of the simulation.

Now, this option is for the change of the loop mode. By clicking this it will rotate 360 forward that is clockwise and anti clockwise 360 and this option will keep moving at 360 rotation rotation and rotating and it will not stop. And this is the interpolation step that's paid off the object to move. I'm not keeping on one if you keep on one, you will not see anything. Just keep at low value. Now, just click on this option played backwards because it is a tip on this direction.

So it will offer clicking on display backward, it will move this side because of this one, it is just moving 360 If I click on this, it will move one time. And afterwards we con this it will move there and after clicking this, it will move 364 and 360 minus that is a clockwise and anti clockwise. And yeah, I've tell you the 0.1 This is the interpersonal Then after it's good speed increase, output speed increase. Yeah, if I keep one it will not show anything I've called for. First of what if it keeps on? Click on to it before move faster.

Click on OK. After afterwards before that I'm telling you about now class after this loss after coming, take the class option, just click Apply don't go into anything yet. Yeah, he will find different types of interference that you can change the name also in the tree specifically, you will find the interference that you have named it suppose I name it as a sa deadbolts it will come as only that type of contact or what is the type of contact will show their contact plus slash will show that and you Between all components, this is my two component it will show between the two components and here it is relevant where the friction get awkward when that hole is there and this is the bar where the friction when it is moved where the frequency get shaking that is showing them and it is a shot starting part.

So, it is when it is start it is yet at that time it widespread very hardly so it is showing that it's not click on this apply. Click ok. Yet you will find that interference that I have given an essay that year it shows and now just click okay finding finding the mechanical analyze let's see what is mean by mechanical analyze first. Let's see what is that analysis mechanism we have to play For the detail of mechanical analyze of the mechanism and review its performance, the Analyze of mechanism commands, we'll just do that the command that I have shown here, I'm doing it, it's located in a do MUB m you can emetics toolbar to analyze the mechanism to create if other mechanism can exist, they can be selected from the mechanism name and the least and the new analyze information will be displayed for a selectable mechanism.

That along the indicated if there is a possible for the simulation why the mechanism the mechanism can be shown for an example that cannot be simulated. Though, in this the option in the mechanism analyze and the dialog box are discussed as below Let us see what is the mechanism name, the name of mechanism being analyzed? Let's see what is the mechanism can be simulated indicate whether the mechanism can be simulated or not. Let's see what is the number of choices, the total number of join in the mechanism? Let's see the number of commands the total number of driving combined in the mechanism. Let's see what is the degree of freedom without the command, the degree of freedom among all part before taking into account, any driving command in the mechanism should be much least one and show the equal number of command.

Let's see what is the degree of freedom with a command the number of degree of freedom In the mechanism, only one driving command our consider should be zero in either performance of simulation. The general name and property have given the name as the up and down motion and the mechanism can be cemented number of joined is one and the number of command is one and degree of freedom without the command is one and degree of freedom without a command is zero. The next part is my second part, and clicking on this visualization. And now I'm saving this file. Click on the Save option afterwards, clicking on Save option I'm saving to this PC. In music in Katya.

I'm giving the name as a RJ for the reloaded sign and save. And here you find that types of which type you want in text or Microsoft you can save the file in both and clicking on the Microsoft Excel Just click Save button. Afterwards, go to that folder where you have saved absenting music and get here. So opening that folder now, this is my folder where I've saved that name as Archie clicking on RJ. Now, you have you can see the database has been generated and you have to just let it adjust and you're you get all types of data's which are there in mechanical analyze afterwards you become the professional in this course, after the end, you will find everything here and this is the rewards and what is the voltage and mechanical analyze that is shown here. This is the Excel file of the RJ that is our revolt.

Join After clicking close this option, it is asking us for I have done some changes there, then clicking close and click this also is a close if you want to do any changes, you can find yours the simulation option and you have the mechanism which mechanism have given the up and down motion and degree of freedom is zero with joint use that is a revolt joint and that is a coincide between these two parts that is a circle and circle These are two centered as a coincide and offset offset is shown here because this is done offset. Then afterward the command with command I have used the angles I know I said My command for use the angle one angle into the fixed part my FAR Part is fixed this part is my fix that is shown in here. And the law and speed expression will study about it later.

And similar set up and down motion. And you're also you can find out what solution I have you want, what command have you and that is the same and you have to change anything, you can just double click on this simulation option. That simulation dialog box will come again you have to do anything changes you can do here also, just click OK. Okay. And I hope that you have enjoyed our first class that is about revolt join. And I hope that also that you have understand everything about the revolt join.

And thanks for buying this course it will make you professional indicator kinematics in further joints. I hope bye for this class and meet you in next US
