- The establishment of a car model based on the theory of sea ( statistical energy analysis ) is discussed
摘要基于統(tǒng)計能量分析方法建立了國產(chǎn)某型轎車的統(tǒng)計能量分析模型。 - The main purpose is applying the statistical energy analysis method to forecast the high frequency wheel / rail noise
本文的主要目的是運用統(tǒng)計能量分析方法對輪軌高頻振動噪聲進行預(yù)測。 - 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
根據(jù)統(tǒng)計能量分析方法的基本原理，以實船為例進行了船舶機械設(shè)備等噪聲聲壓水平的估算和船舶艙室噪聲預(yù)示，并對影響船舶艙室噪聲水平的各種因素進行了分析，提出了減小船舶艙室噪聲水平的方法。 - 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
首先根據(jù)統(tǒng)計能量分析方法中子系統(tǒng)劃分的原則，將整個結(jié)構(gòu)系統(tǒng)劃分為：鋼軌的垂向振動子系統(tǒng)、車輪的徑向振動子系統(tǒng)、車輪的軸向振動子系統(tǒng)及聲空間子系統(tǒng)共四個子系統(tǒng)；并且建立了子系統(tǒng)間功率流平衡方程。 - 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
目前對噪聲預(yù)示主要有三個方法：一是相似結(jié)構(gòu)外推法，包括頻率響應(yīng)法和比例法等；二是傳統(tǒng)的模態(tài)方法，包括有限單元方法( finiteelementmethod , fem ) 、邊界單元方法( boundaryelementmethod , bem )等；三是統(tǒng)計能量分析方法( statisticalenergyanalysis , sea ) 。 - It's difficult to find statistical energy analysis in a sentence. 用statistical energy analysis造句挺難的
