Hi,
I want to make a dynamic Analyse of a rotating (cam)shaft in Ansys. My target is to implement this shaft in a Multibody system program. For this, I need the Systemmatrix, the Inputvector and the Outputvector. Ansys is calculating with this formula:
M = Mass Matrix
B = Damping Matrix
C = Stiffness Matrix
F is the Input Vector (which I need)
and X the Output vector.
Is it possible to extract the full Systemmatrix or do I have to calculate it myself (Matlab) with M,B,C ?
Formula for the Systemmatrix is:
A=[0 , I ; -(M^-1)*C -(M^-1)*B]
If the direct extraction is not possible, how can I extract the other matrices M,B,C and of course X and F? Someone knows the code or a solution for my problem?
