Squeeze Film Disc
Model ID: 14105
This benchmark model computes the total force acting on a vibrating disc in the frequency and time domains and compares both results with expressions derived analytically. When the vibration amplitude is small enough that the system is linear the frequency and time domain results agree well with theory. Larger amplitude vibrations, which result in a non-linear response that cannot be modeled in the frequency domain, are explored in the time domain, and compared against analytic solutions.
