Abstract
Formulations of the reverberation matrix method (RMM) are presented for the dynamic analysis of space structures with multiple tuned mass
dampers (MTMD). The theory of generalized inverse matrices is then employed to obtain the frequency response of structures with and without
damping, enabling a uniform treatment at any frequency, including the resonant frequency. For transient responses, the Neumann series expansion
technique as suggested in RMM is found to be confined to the prediction of accurate response at an early time. The artificial damping technique
is employed here to evaluate the medium and long time response of structures. The free vibration, frequency response, and transient response of
structures with MTMD are investigated by the proposed method through several examples. Numerical results indicate that the use of MTMD can
effectively alter the distribution of natural frequencies as well as reduce the frequency/transient responses of the structure. The high accuracy,
lower computational cost, and uniformity of formulation of RMM are highlighted.
