Hi
I have MDOF equation:
MX"+CX'+KX = F(t).
Say the order of each matrix is nXn. I want to reduce the order of the matrices.
I will find the eigen vectors and get modal vectors matrix phi. I will pick some dominating frequencies say around 24 modes.
then reducedM = phi'*M*phi.
Now reduceM has an order of 24X24. Will this procedure give me satisfactory result at last? or are there any other methods to reduce the dof's.
Thanks in advance...
