Reply To: Vibration isolation

I want to simulate a situation where the lower part of an object is excited up and down at 400Hz with a displacement of 10mm and a constant pressure is applied to the upper part, and check the difference in displacement change between the lower and upper parts of the object. In transient analysis, the pressure condition at the upper part, I added a sin function as the displacement condition at the bottom, but it did not solve the problem. I wonder what the problem is. I'm also curious how this can be solved.
