We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

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.
