Hello,
I was tring to model a square plate tilting about the center line with the squeeze film damping effect. I build two tiny beams to connected the square plate, make sure the plate can rotate about these two symmetric beams. And also the two tiny beams can supply the tosional stiffness. But, I just need to simulate the eigenfrequency of the tilting plate without the calculation of the connected beams. The problem is:
1, How can I seperate the connected beams in the eigenfrequency calculation?
2, Is there a better way to supply the tosional stiffness without bulid the connected beams?
3, I already set the square plate as a rigid domain using Rigid Connector. But when I changed the Young's modulus of the plate, the eigenfrequency is still changed? I really confused. Could you tell me why? Or the model is not right.
The model what I already build is attached, does somebody know this kind of problem, please give me some advise, thank you very much
