How do I get critical frequencies

I compiled a simmechanics model of rotation of a rigid rotor on two flexible supports. But in the range from 0 to 10,000 rpm. The reaction of the supports does not change and the position of the rotor does not change. Can I get their modified values to simulate oscillations in the first, second, third waveforms (modal) Rigid rotor on flexible supports?

1. You can use a global variable to utilized the variable.
