What is the ideal tool for this case?

Hello everyone,

Could somebody help me with a tip for this case?

I have a case with gears, axles and rollers. In your opinios which is the best tool for stabilize the rollers? As shown below, there are a lot of rollers, but I don´t know how to stabilize all of them. Should I use spring element with low stiffness in each roller or some kind of macro to represent the rollers? Any idea?

I´ve hiden one gear to see better how it works.

Thank you in advance,

Luiz

What kind of analysis you need to perform here?

Depending on what you need, and for how long you want to run that, i would go for explicit analysis (in OptiStruct or Radioss). It would handle much better the contacts.

Hello @Adriano A. Koga, thank you for your reply.

It´ll be a static linear analysis with Optistruct. My main doubt is about how to stabilize the rollers, presented in red in the picture. As you can see there insn´t any kind of part that restrict the axial movement.

In this case, which tool should I use to stabilize the rollers?

Thank you,

for the axial movemente, you could simplify it and add a constraint in the axial direction only.

But again, depending on what you really need to evaluate, there are several other simplifications possible.
