Unnatural acceleration in step

Recommended Posts

I am analyzing the wheelchair while driving a step.

When going down a step, I will accelerate suddenly and I can not get an accurate value.

Is it a mesh problem?

Is there a solution?

Please tell me if there are similar cases.

Hi,

 

Thank for sharing the files. From the animation, it looks like the problem is coming from the contacts.

 

Let me check the setup and I will get back to you soon.

Hi @TomokiAoki

 

I ran the same model in 2017 and the animation looks fine. 

 

Could you please update to the latest version and check at your end?

If the tire touches a right angle (90 deg), will it be difficult to calculate?

I don't think so, if modelled correct.
