statistical energy analysis meaning in Chinese
统计能量分析
Examples
- The establishment of a car model based on the theory of sea ( statistical energy analysis ) is discussed
摘要基于统计能量分析方法建立了国产某型轿车的统计能量分析模型。 - The main purpose is applying the statistical energy analysis method to forecast the high frequency wheel / rail noise
本文的主要目的是运用统计能量分析方法对轮轨高频振动噪声进行预测。 - But this is not a problem for ship structure which is thin and good ductibility . the basic equation of statistical energy analysis is deduced in this paper , the shipboard noise of 295 , ooodwt vlcc is calculated based on sea , the factor effect on the noise of shipboard is discussed and some measurement to reduce the noise level is suggested
根据统计能量分析方法的基本原理,以实船为例进行了船舶机械设备等噪声声压水平的估算和船舶舱室噪声预示,并对影响船舶舱室噪声水平的各种因素进行了分析,提出了减小船舶舱室噪声水平的方法。 - 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。 - 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 ) 。
