Power flow analysis for a floating sandwich raft isolation system using a higher-order theory

Choi, W.J., Xiong, Y.P. and Shenoi, R.A. (2009) Power flow analysis for a floating sandwich raft isolation system using a higher-order theory Journal of Sound and Vibration, 319, (1-2), pp. 228-246. (doi:10.1016/j.jsv.2008.05.020).

Record type: Article


A higher-order sandwich theory is implemented in conjunction with an equivalent mobility-based power flow progressive method to determine power flow for a sandwich configured floating raft vibration isolation system. The power spectrum changes in whole frequency range effectively when core materials’ properties change. It is also shown that the loss factors of the sandwich configured floating raft influence the power flow transmitted to the foundation effectively in the medium- to high-frequency range and that the resonant peak cannot be avoided by increasing damping only in high-frequency ranges which is not found in floating raft isolation systems with isotropic beams.
