Abstract

To analyze the influence of the nonlinearity of the floating raft vibration isolation system, the theory of flexible multibody dynamics was used here to model the rigid-flexible coupling nonlinear floating raft vibration isolation system. The dynamical characteristics of the model were studied with ADAMS software and some typical nonlinear phenomena, such as subharmonics, superharmonics and attractor coexistence, were observed through time domain analysis.
