ME617 - Handout 7 (Undamped) Modal Analysis of MDOF Systems

In MDOF systems, a natural state implies a certain configuration of shape taken by the system during motion. Moreover a MDOF system does not possess only ONE natural

Modal Analysis of MDOF Systems with Proportional Damping

i.e., the j-modal damping ratio increases as the natural frequency increases. In other words, higher modes are increasingly more damped than lower modes. The response for each modal coordinate satisfying the modal Eqn. Mq Dq Kq Qj j jj jj j j n , 1,2... is obtained in the same way as for a single DOF system (See Handout 2).
