Hello everyone,
I am trying to calculate the eigenfrequencies of a structural system in COMSOL with the bolt pretension considered. The structural system is consisting of two circular plates, a bolt, a washer, and a nut. The two circular plates were connected using the bolt and they are considered "Assembled" instead of "Unioned", i.e., the contacts are considered.
It is my first time using the module and in COMSOL and I can not find a detailed reference. The in the application libraries was used by me as a reference but it seems there was something wrong with my settings and I can't find it. My calculation file has been attached as .
Does anyone know how to solve this problem or where to find a detailed reference?
I would appreciate it if you could kindly give your advice.
Wish you all the best and thank you for spending your time on my question.
Regards,
Hao Qiu
