摘要: 利用统计能量分析理论建立了水下航行器实航与台架试验的振动相似律分析模型,分析了水下航行器实航振动级与全功率台架试验振动级之间的关系,给出了二者的振动相似性规律。

关键词: 振动 , 相似律 , 统计能量分析

Abstract: The laws of vibration resemblance for under-water vehicles under conditions of shipping and platform tests (when provided with full power drive) are analyzed by statistical energy analysis (SEA). The resemblance is obtained between the shipping vibration levels and those on testbeds un?der full power drive. Thus it is convenient to predict the vibration levels of a shipping vehicle,and the structure-born sound levels.

Key words: vibration , law of resemblance , statistical energy analysis (SEA)
