I compared results with real experimentation and comsol model. Both are coherent but not with my model.
I choose a 2 flex beam model with 3 dof by node (2 translation and 1 rotation). Then I wrote down M and K matrix and try to solve det(K-w²M)=0, with computer in the first place, but results...

I tried a 2 x (mass spring system) or beam...
