摘　　要：针对船用浮筏隔振系统,基于统计能量分析法建立了一种浮筏隔振系统的统计能量分析模型,采用振级落差方法估算浮筏隔振系统的隔振效果,并与试验结果进行对比,理论预测与实测值基本一致,在一定精度范围内满足工程估算要求。Using the statistical energy analyzing method （SEA）, a model for analyzing the marine floating raft isolation system is established. The vibration isolating effect of the raft isolation system is measured and analyzed by means of the Vibration Level Difference method. Comparing experiment result with theoretically estimated value is civen out. It shows that this method can meet general need of engineering design.
