Classical modal analysis is extended to deal with general non-viscously damped multiple degree-of- freedom linear dynamic systems. The new method is similar to the existing method with some modifications

Response of MDOF systems - Chula

Modal analysis • is a method for solving for both transient and steady state responses of free and forced MDOF systems through analytical approaches. • Uses the orthogonality property of the modes to “decouple” the EOM breaking EOM into independent SDOF equations, which can be solved for response separately.

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).

Today, modal analysis has become a widespread means of finding the modes of vibration of a machine or structure (Figure 3). In every development of a new or improved mechanical product, structural dynamics testing on product prototypes is used to assess its real dynamic behavior. Figure 3: Modal analysis of a car body. 2.
