थोड़ा MultiBody Dynamics

Hello people !
Just as a usual timepass, I made this MultiBody Dynamics (MBD) model.
Let me spread ग्यान about MBD.
Those who did the CATIA/Pro-e course in the college might know this assembly.
Well I went a step further with it and made it into a simulation using Altair MotionView.
For those who don't know CATIA or Pro-E (yet) or anything to do with CAD/CAE:
These components were drawn and assembled on the CAD software CATIA and saved as an IGES. Then imported in Altair HyperMesh (pre-processing module in Altair HW) and meshed with element size 15. Using a special trick (which is unrevealable here, took time to work it out, बोलेतोह I am still learning, समजा? ), the meshed model was brought into MotionView (MBD module in Altair HW). Joint relationship was established between components, a motion to the shaft was given and there we are, this is called putting जान in a बेजान model !
Hope you liked it.
