Calculates the modal parameters and response of multi-degree of freedom linear system subjected to dynamic forces.
Calculates the response of multi-degree of freedom classically damped linear system subjected to dynamic forces (using Modal Superposition method [1]).
function Result=MDOF_simulation(M,C,K,f,fs)
input:
M:mass matrix (n*n)
C:damping matrix (n*n)
K:stiffness matrix (n*n)
f:external force matrix(n,N)
fs: sampling frequency
where n is the number of degrees of freedom, N is the length of data points of dynamic force
Output:
Result: is a structure consist of
Result.Displacement: Displacement (n*N)
Result.Velocity: Velocity (n*N)
Result.Acceleration: Acceleration (n*N)
Result.Parameters.Freq=Natural Frequency (n*1)
Result.Parameters.DampRatio=Damping Ratio (n*1)
Result.Parameters.ModeShape=Mode Shapes Matrix (n*n)
