  1. The wheelchair is running on a flat road. Obstacles with steps appear during driving. I want to take the acceleration value obtained by that impact. But why does the value change just by slightly changing the distance from the obstacle? For example, when the distance to an obstacle is 1000 [mm], I changed 1 [mm] or 2 [mm]. Is it a mesh problem? The mesh level is set to 5 when importing.
  2. I am doing a simulation that down steps with a wheelchair. I am using Hyperworks 2017.2. I would like to change the step and output the acceleration for each step. However, a good waveform is not output and the value is not appropriate. I think that it is a matter of contact penalty, but I am in trouble because I can not find a suitable penalty. Please give me advice. It is also possible to share the file if necessary.

  4. Thank you, Prakash Pagadala I'll try update. I have one more question. If the tire touches a right angle (90 deg), will it be difficult to calculate?
  5. I am analyzing the wheelchair while driving a step. When going down a step,the wheelchair 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.
