Rotation simulation

  Hello,
  I want to make a simulation in which I can examine the stresses caused by the sudden stopping of a mass while rotating at 60 rpm.
  Could you please advise me if this is possible?
  Thanks!

  Use a Transient Structural analysis. What causes the sudden stopping? Is it a brake torque applied to the shaft?

  It stops with the sudden shutdown of the motor used to rotate.

  Okay, so if you have a shaft in the model, use a revolute joint on that shaft circular face where it might be cut at a bearing location or some flange. Then use a joint load to control the motion to simulate the sudden stop. That could be entered as tabular velocity data. The table can have angular velocity that is equal to 60 rpm, and ramp down to 0 over some short time and stay at 0 while the transient computes the response of the rest of the structure to that shutdown. The initial conditions of the parts will have to include the 60 rpm angular velocity.

  Thank you for your advice sir.
