I have a harmonically forced 2 degree of freedom system that I am trying to find the steady state responses to. I have determined the two equations of motions and found the [m], [k], [c], and {f} matrixes.
However when i try to use eigen analysis ( q=phi'*[m]*phi ) I am unable to uncouple the two equation of motion to allow me to solve the system as two independ. single degree of freedom systems.
I believe I have correctly set up the EOMs... what other methods can I use to solve for the x and y steady state responses.
PS i am using matlab.
