topology optimization with dynamic loads
Altair Employeehi there,
I am working on a topology optimization problem with HW 14. More detailed, it is a crank set of a bicycle which should be loaded with a cyclic load and a static load. The cyclic load simulates the load induced by the cyclist. The static load simulates the cyclist who stays on both pedals.
For my problem I guess the ESLM should work, but I went through the examples for Multi-body Dynamic Analysis and could not find how to implement a cyclic load. Another idea is to rotate the crank set and induce a load at a specific time and place. But I have not found a tutorial or information how to do that yet.
Another idea was to use a transient subcase for the cyclic load, but it seems that topology optimization doesn’t work with transient subcases (read on another thread).
Do you have any idea how to implement cyclic loads as a subcase and do a topology optimization?
I appreciate your help

Hi Martin,
Optimization with transient cyclic loads is under development but you can do a frequency response optimization
