Welcome, everyone for a net join that is roll call join. Let's see what is a roll call join the roll call joint is a translation and rotational join, it is an element of four degrees of freedom and allows one per rotational as part is a roller and that one translation additions to cover that is ACO It is used when one parties need to move along the another for maintaining without or sliding. In other words, the one roller along the other. A good example is a roller bearing and the inner bearing will be spin while the outer Bearing will rotate about the axis it requires wire by the mechanism or roll called joint control with the land command let's begin so first just click on Start go to digital NACA any you find a third option d m you can really just click on D and you can after clicking on D and you can do text you will get this interface now just click on Insert click on new part you're going with me plus click double click on this part no just click on this x y plane click schedule two dots click on this circle clicks from origin one more circle with a smaller one.
No giving the damage any no one is 28 Okay, and this one is 160 Okay, this 160 okay for me, now exit it, you bad 20 Okay, now this is phase finish, just double click on product for making another part click on Insert click on new part for making another part. This part one is my finished Part Two I'm going now just double click on part two, just to repeat here part two. Now skit similarly that only xy plane sketching one more click on this axis click here and now here you have to go to a circle same net procedure only making this one circle smaller from let's click this one 2018 we'll get 20 this drag it out. And this one I'm getting nearly allowed 60 and why Masako? Anywhere you can you wait for the reference? It doesn't need I'm getting called the recipe reference only.
Just click one more, just click this one and this one is phase very important for the role, role culture and we have to make this tendency. If it doesn't have tendency it will not work in our own culture. Remember and just drag it this circle doesn't matter anything. Just keep it it is for the fence click Exit gate clicking on exit. Okay, bad option. I'm getting 20 mm Okay.
Now This is part two and part one which ready now just double click on product. Then click on Insert, click on new part just click Yes. And from the center plane, just click here part one. And as double click on this part three and xy planes catch just press this click this one and projectory element this turns to ello then click on exit giving bad or worse 20 I'm giving this as mirror direction and till you know granted Okay, now on this part only part three we have to draw on our surface kitchen you'll find it slot option, just click on the slot On this center to this center it doesn't matter anything you can draw you're further making the road. Let's click on this and this outer surfer click Go inside and concentrate. Okay.
It slowly coincide is clear exit is coincide yet, you have to give just an outline. I'm just writing it outside doesn't matter anything great exit just feel bad and giving the pair of one emolia doesn't own this much more and this is the joint Everything is ready now time for the changing of the script property or all percentage changes color you can write the part name description and this description will show in the Bill of Material It's now time for the graphic change any graphics color to am doing a low transparency apply okay for everything I'm changing the color property apply if genuinely the colors nothing else. Now go to double click on product. Let's double click on product click on we have to make a to revolt sign for making your return just click on Insert the new join to all join. I have explained about the revolve join in previous classes you can watch that tector and everything you will know from that.
Just click on new mechanism. Click ok. navigate down the line one and just click on this outer surface for the line to just click on this surface. We'll get to line two and four this plane Just click this one and this one and keep this opposite angled one don't give the angle ruin just click on OK Same for this one also click on Insert, record new join click on to all showing and same same mechanism don't do new mechanism just click on the surface and this one click on this crane this one and this one give it offset Don't get angry when you're also if you doesn't know anything about derivative interest see the previous video first lecture on from there you will get everything out of the river chain. Now everything is ready just click on Insert click on new join and finally the roll call join protocol join your you have to select this row and this one.
It must be tenancy if it yeah having the cap it will doesn't kill this tip. Remember there Remember this you have to give attendance here remember this one yeah this one we should have a tendency and give Lastly, land to one click OK. Now everything is ready. Finally, see the what is mean by the fixed part once more, let us see what is a fixed part of fixed that is the anchor symbol, the location in a space of a part in the assembly choose this option one apart is a can emetic and must be fixed before the simulation is possible. It is the location on a do kinematics that toolbar icon I will show there that please note that the mechanism need to exist before a part can be defined. This was the fixed part click on fixed part and this is my fixed now finally, we have to look at the mechanism Canvas Today now let's click on ok click on Insert, click on simulation yeah the value 180 we have to change this we have to see when it is happening 180 we have to give more than 180 here when it did sorry, here it is getting 180 so from here to here distances 180 we have to increase Yeah, I'm getting started by two Okay.
Is there only one small just changing to you have to check 360 you have to go check check here it is 360 and this distance does depend on the elbow circle and the blue circle. What they have in the diameter it is depend on them. The part is depend on them. Here it is 360 we have to go and give it more 180 and giving No, as high as 60. Let's see. For fy 16, it's coming year.
It's going beyond it. Just giving fy 20. It's okay for FY 2520. Click ok. Click tip. Just see what is mean join and key position on exit. 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 auction is not activated, the mechanism can be will return its original 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 our being to check recheck throughout this simulation. Now click on this key portion exit and insert.
Let's see what is invalid simulation first simulation player and commands. This symbol should jump to start or return instantaneously to the beginning position of the simulation regardless of the current location. This symbol show the step backward. The step backward one frame at a time. This symbol show played backward. Play the simulation in reverse from the current step until it reached the beginning.
This symbol show pause the simulation this symbol show play forward. Play the simulation forward from the current step. These symbols show the step forward a step forward to the simulation and the one frame per play this symbol so jump to the end, the escape die instantaneously to the end of the simulation. And now am giving this one as let it beat I'm giving this as a it will go forward and backward anti clockwise clockwise don't give this one just clip as low as possible click Play button and this is because it's going clockwise anti clockwise because of this, if I click on this, it will rotate and rotate and rotate your arm holes even because you have to for the understanding yet and giving this one this one this whole will help us to know is whether it is rolling or not. Well, that one I've given the whole The world doesn't matter.
You have to remember that we have to give tangency now it's fine. To find a cash on cash and just click on Apply relevant for living. See how much clashes getting Oklahoma's friction is getting aquaria see understanding what was the friction it's good within a euro just clicking OK. Now click ok if you want to change anything you can change here in application you find a simulation you can find a mechanism you can change this mechanism also the degree of freedom is one to join, which we have given the force was revalued. Second was a revolt and third we are going to finally know roll call which also important joined for us and now it's time for them analyzing mechanical analyze. Before click on analyze, click on mechanics or you can click on this symbol also clicking on mechanical analyze. Let's see what is the mechanic can analyze for Lexi.
What is that an lso mechanism? We have to perform the detail of mechanical analyze of the mechanism and review its performance. The analyze of mechanism commands will just do that, that come on that I have shown here. I'm doing it, it's located in a deal and mew de 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 analyzed under dialog box are discussed as below.
Let's 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 choice, the total number of joints 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 combined 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 degrees All freedom in the mechanism, only one driving command our consider should be zero in either performance of simulation.
No, no, we notice everything that's clicking on it is show is showing that rotation. This is offset. And this is a rotational isn't getting awkward between this and this one is part is fixed. This part is fixed, it's showing that and click on Save button. Now this is my role culture and simply I'm getting RJ, which is the roll call join. Or you can give full name around see j, mentor Oracle join.
So you can get it in anything name to see whether Where are you saving a file and the shopping that folder have given the name as role culture and just opening that old culture in here. And your data is everything what data we have provided, and this was a mechanical analyze data, just closing it that you can watch in your laptop, a laptop, everything in full in detail. Now just closing it now and if you want to do anything changes click on simulation, you can do any every changes. And this was ours. If we keep on one it will show this one speed. Just remember don't give that much speed and this was our sorry, this was was our given to the void and one roll call join that was our main joint roll call join.
I hope that you have understand everything over the role culture and if you have any doubt you can ask me questions. And I hope you have understand everything. So make your next class with another join. Bye for this class.
