hello everyone today we are going to learn how to animate this Motion in Simmons NX using simulation of anex so let's start with this tutorial first of all you have to define the links as we have studied the kinematics of machine where we have certain mechanism and in those mechanism there are certain links and then we are going to define the joints so this is the basic need of the simulation let's go to the Navigator which is said to be as motion Navigator after that I have defined certain motion bodies and Joints so if you are using the previous version of NX then the motion body is named as link so it's basically going to define the links or the number of bodies which we are going to use in the mechanism so you just simply have to click on the motion body and there is a toble here in the settings which defines the fixed body without any joint so by using this toggle you can fix any body you want in the mechanism so I have fixed three bodies here like you can see 1 2 and 3 if I just rotate the view then it is four actually basically I'm counting these bodies as one so just to fix them you have to just click on motion body and then activate this option and then select the all bodies one by one like this currently I'm canceling this because I have already selected the fixed bodies so just cancel it after defining the fixed bodies I have defined certain motion bodies here which I'm going to use in the simulation so in this way you can Define the bodies and make sure while defining the motion bodies like this one this one make sure that the toggle is in inactive State okay otherwise it will fix the other bodies as well so be careful while using this option just cancel this once you are completed with defining the motion bodies like you can check here we have defined certain motion bodies here so once we are completed with the motion bodies we have to define the joints so that we can Define that what kind of motion is going to take place among the mechanism let me set the graphics window so that you can have a clear vision of the joints here it is a fixed joint like you can see I have given a fixed joint between this member and this member just go to the edit then this is set to be as the action body and this is the base body okay once we are done with the fix joint like here we are going to define the slider joint this is the foundation of this mechanism let me show you why if I just go to change the view to wif frame then you can see this is the maximum limit of this piston like from this point to this point so you have to just calculate this distance from this let me change the let just reset this just go to object from this Edge to this Edge okay so you can see this is the minimum distance is 28 something so you want to cover this distance in what time that will be said to be as the velocity for this slider in this way you can achieve the calculation for this mechanism like if I just go to the slide then edit this the action body will be the red one and the base body will be this gray one okay and in the driver you'll get the option of polinomial and in the polinomial I have given the velocity as 28 something divided by 3 because I want the simulation to be get performed for the 3 seconds okay so in this way you can achieve the calculation for this slider next I have given the rotational motion here to this body just go to the addit and here I have given the revolute then the motion body is this and the base body is going to be this then this is the drial that how much angle is going to be get covered in what time as these are three defined joints which are defined by me so if you want to define a new one you have to just go to the Joint like this and here you have number of choices regarding the type of joint and then you have to choose the action and the base body and then the driver basically I have given three drivers here only first to the slider and then to this and the rotational one and others are utilizing that driving motion okay so here we have given the drial here we have given the slider joint again to this pink part and this pink part will be get slided along the brown body like this and we have the driver here that how much distance is going to be get covered in what time then we have the fix joint here let me just rotate this if I just go to edit this is the action body like you can see this is the action body and this is the motion body and this is fixed to this then we again have a fixed joint this is the motion body and this is going to be the base body the gray one again we have the fixed body for the wheel like this this is going to get fixed with the inner body then we have the sliding joint for this one and this is going to get slided over this just click on okay and I have given the driver as well of 4 mm per second you can give the same boundary condition so that you can achieve this kind of mechanism and for all these three like first second and third for all these three I have used the revolute joint with no drial like if I just go to edit so you can see that what is going to be the action member and what is going to be as the base member so here the action is going to be this and the base is going to be this one and the driver is not here then for the joint 004 is this one which is here and for here this is the action and this is the base and the driver is said to be as none then for the last joint these both bodies okay so here we have the revolute and the base is going to be this shaft then the driver is none just click on okay and be careful as uh for defining the motion bodies I have defined this as a single body this member and this member okay so this is just a trick for this mechanic ISM and once you are completed with the motion bodies and Joints you have to go to the solution and in solution you have to define the solution and time that at what time do you want to end this solution and then hit okay then you will get an option here just do the right click and then click on solve so it will solve all the equations which are being possible for the boundary conditions you have given to the system once you have completed with with all of this just you have to right click on the customize and in customize you have to just search for the animation player just go to the commands and then search for animation player once you get the intended command you just have to drag and drop so that you can get the icon in the ribbon then just click on animation player after that you have to just click on play like this and I have switched on the retrace path so it will play like this so in this way you can get the animation of the same so that is all in this tutorial thank you
