Wheel on an inclined plane

Hi,

 

I have modelled a wheel on an inclined plane and given gravity load to the wheel expecting it to roll on the inclined plane. Rotational constraints are set free. But the wheel is sliding on the plane instead of rolling. what may be the reason or am i missing something?

 

Thanks in advance.

 

Regards,

Bhavana.

    Hi,

     

    Could you share more information on your project like what type of contact interface you defined? Hope you would have applied some load along with gravitational load because in Radios we cannot run job only with gravity load.

    Imposed displacement along with rotational Dof along incline plane with Type7 contact should work. If possible please share your  model through FTP file transfer.

    Hi,

     

    Even you can try with below initial velocity.

    /INIVEL/AXIS - Initial velocities for translating and rotating components

    Hi Rahul,

     

    Thank You.

     

    It means cant we run the jobs only with gravity load in Radioss?

     

    In our case first we tried simulating a block on an inclined plane with a gravity load. Under gravity the block is sliding and the same sliding behavior is happening in the case of wheel on an inclined plane where we expected the wheel to roll. we have given type 7 contact between the wheel and inclined plane.

     

    Could you please let me know the reason for this behavior?
