My apologies Naoki san. The endstop is ok then.
The issue is that both sides of the damper are connected to the rotary inertia, so the torque is R*(V1-V2) and both velocities are the same. You need to ground one end of the damper:
Thank you, It works well.
Originally, Performance analyzer said Rotaryload consums a lot of Cumulative contribution.
I found osilated torque was input to rotaryload , So I tried to reduce osillation by damping effect like this.
But caliculation speed didn't improve.
Could you give me advice for this issue?
Difficulty to give good advice without the model, but you can try:
If it fails, don't hesitate to share your model with the support line.
