统计能量分析 meaning in English
statistic energy analysis
statistical energy analysis
Examples
- According the principle of the statistical energy analysis method , define subsystem the whole system into four subsystem : subsystem of rail ' s vertical vibration , subsystem of wheel ' s vertical vibration , subsystem of wheel ' s lateral vibration and subsystem of acoustic space . then define the power flow equation between the subsystems
首先根据统计能量分析方法中子系统划分的原则，将整个结构系统划分为：钢轨的垂向振动子系统、车轮的径向振动子系统、车轮的轴向振动子系统及声空间子系统共四个子系统；并且建立了子系统间功率流平衡方程。 - The data regression processing method based on fuzzy mathematics theory is proposed to get the middle frequency band simulating result based on finite element result of low frequency band and statistics energy analysis result of high frequency band to get a complete frequency band result and solve the middle frequency band result processing problem in the simulation of floating raft isolation system
摘要为了解决浮筏隔振系统仿真结果的中间频段数据处理问题，基于浮筏隔振系统低频段的有限元分析结果和高频段的统计能量分析结果与试验结果的对比分析，提出采用模糊理论进行数据回归处理来得到中间频段的仿真结果，从而提出一种估算浮筏隔振效果的方法。 - There are three main approaches to predict the noise level : similitude structure method including the frequency - response method and proportion method , modal method including finite element method ( fem ) and boundary element method ( bem ) , and statistical energy analysis ( sea ) . the advantage of similitude structure method is to give the predicting data fast , but it has some error because of dealing with rough similitude parameter and mass load
目前对噪声预示主要有三个方法：一是相似结构外推法，包括频率响应法和比例法等；二是传统的模态方法，包括有限单元方法( finiteelementmethod , fem ) 、边界单元方法( boundaryelementmethod , bem )等；三是统计能量分析方法( statisticalenergyanalysis , sea ) 。
