Find resonance peak with parameter sweep in vibration mount

Please login with a confirmed email address before reporting spam

I'm simulating vibration isolation mount, and I can get the transmissibility function by getting the value of acceleration of mass and base, and by dividing them. Then I can successfully get the graph of mass-spring-damper system. The mount is just simply designed as block with some thickness, and I want to get the value of resonance frequency by sweeping the thickness of mount. I firstly tried eigenfrequency study, but it just shows strange complex number eigenfrequency, whose real part is 10^-4 scale.

The algorithm that I want to realize is this : I set thickness with some value, and get the frequency response, find resonance frequency. I sweep the thickness, then I can get the graph of thickness-resonance graph

How can I do this algorithm in COMSOL? I feel really gratitude to your help in advance.
