Hi, i´ve generated a complex multi-body system of a front axle from a car. Is it possible, to calculate the eigenmode and eigenfrequency from the whole front axle with simmecxhanics 2nd generation (the dynamic stiffnesses/dynamic characteristic curve is known of the bearings/bushings in 2nd gen)? If it´s possible, how can i use that? Or is there another possibility to calculate that? Do i need an another tool for that? Kind regards

If you have access to Simulink Control Design, you could try linearizing your SimMechanics model, which would give you a State-Space system with matrices A, B, C, D.
Then, you can take the A matrix to find the eigenfrequencies and modes:
[eigModes,eigVals] = eig(A)
