How to get eigenvalues and eigenvectors from a mass and spring model build by simscape?

If I build a model with springs and inertia with simscape i can linearize the model and calculate a frequency response. What about the eigenvalues und eigenvectors of the model?

You should be able to get the system matrices (A, B, C, D) for your linerized model. The eigenvalues for A can then be calculated using eig( ).
