摘      要：Choosing the equipment with good shock-resistant p erformance and taking shock protection measures while designing the onboard sett ings, the safety of onboard settings can be assured when warships, especially su bmarine subjected to non-contact underwater explosion, that is, these means can be used to limit the rattlespace (i.e., the maximum displacement of the equipme nt relative to the base) and the peak acceleration experienced by the equipment. Using shock-resistant equipments is one of shock protection means. The shock- resistant performance of the shock-resistant equipments should be verified in t he design phase of the equipments. The FEA (finite element analysis) software, for example, *** ○R , can be used to verify the shock-resistant performance. *** ○R and *** are used for modeling and analyzing the floating raft vibration isolating equipment. The model of the floating raft and the floating raft vibration isolating system are theoretically analyzed and calculated, and the analysis results are in agreement with the test results. The transient response analysis of the system model follows the modal analysis of the floating raft vibration isolating system. And it is used to verify the shock-resistant performance. The ana lysis and calculation method used in this paper can be used to analyze the shock -resistant performance of onboard shock-resistant equipments.
