Response of MDOF systems - Chula
pioneer.netserv.chula.ac.thModal 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.

mech.vub.ac.beToday, 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.
