Abstract
The previous chapter carries out the performance analysis of particle dampers attached to single-degree-of-freedom (SDOF) structures, with an emphasis on the structural dynamic characteristics under correlated stationary random excitations in the x and y directions. Based on such investigation, in this chapter, the main structures are generalized to multi-degree-of-freedom (MDOF) ones, and the damping performance of particle dampers attached to MDOF structures is systematically analyzed. Especially, the external excitations have been expanded from stationary random excitations to nonstationary random excitations, which are more consistent with the actual situation (Lu et al in J Vib Control 17(10):1454–1471, 2011, [1], Lu et al in Sturct Control Health Monit 18(1):79–98, 2011, [2] and Lu et al in J Sound Vib 329(26):5415–5433, 2010, [3]).
