hi,

I modeled a gear and want to find out angular velocity of the gear,

how to do that,should I include any expression and how to do with that

Thank you

    Two ways you can do this:

    1. Create a displacement output on each Gear body.  You will get displacements (and rotations) of the body, you could also request velocities, etc.

    2. Create a displacement output for the joint that attaches the gear body.

    HI,

    I created the contacts and gave the input motion but both the gears are not rotating completely

    Can you please check with this

    Hi Lokesh-

    I took a look at your model, but there were not graphics included, so I couldn't test.

     

    However, your contact settings look a bit suspect to me.  I would suggest looking over the section in our help 'Best practices for contact modeling'

    Your stiffness value is likely too low, and you should use the Advanced option 'find precise contact event'

     

    On the transient integrator settings, change the max step size from .01 to .001

     

    Best,

    Chris
