Hello Zhao,

It is okay that the speed is fast in the experiment. We need to keep the same speed in the simulation and troubleshoot the problem :).

Plot the internal, hourglass, and sliding energy together on the same graph without kinetic energy. What does it look like? Please post a screenshot.

Also, check the RCFORC (contact force) between the blank and the  wheel and compare between case 1 and 2. If the contact is the problem, the contact force should be much larger in case 2.

 

Reno.
