本文的主要目的是運(yùn)用統(tǒng)計(jì)能量分析方法對(duì)輪軌高頻振動(dòng)噪聲進(jìn)行預(yù)測(cè)。 - 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(jì)能量分析方法的基本原理，以實(shí)船為例進(jìn)行了船舶機(jī)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(duì)影響船舶艙室噪聲水平的各種因素進(jìn)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(jì)能量分析方法中子系統(tǒng)劃分的原則，將整個(gè)結(jié)構(gòu)系統(tǒng)劃分為：鋼軌的垂向振動(dòng)子系統(tǒng)、車輪的徑向振動(dòng)子系統(tǒng)、車輪的軸向振動(dòng)子系統(tǒng)及聲空間子系統(tǒng)共四個(gè)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(duì)噪聲預(yù)示主要有三個(gè)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(jì)能量分析方法( statisticalenergyanalysis , sea ) 。
百科釋義
Statistical energy analysis (SEA) is a method for predicting the transmission of sound and vibration through complex structural acoustic systems. The method is particularly well suited for quick system level response predictions at the early design stage of a product, and for predicting responses at higher frequencies.
