引言

基于純電動裝載機技術(shù)路線不同、噪聲模型不同、噪聲品質(zhì)不同、相同規(guī)格瞬時功率差異較大，本

文件從純電動裝載機的工作原理和噪聲產(chǎn)生的機理出發(fā)，針對純電動裝載機的結(jié)構(gòu)特點和不同技術(shù)路

線，探究純電動裝載機噪聲的產(chǎn)生規(guī)律，尋求針對純電動裝載機噪聲的試驗方法，并進行科學評價。為

了解決這一問題，制定了本文件。

本文件采用模擬的動態(tài)試驗條件代替實際的作業(yè)循環(huán)試驗條件。模擬動態(tài)試驗條件提供具有可

重復性和代表性的噪聲發(fā)射數(shù)據(jù)，而實際的作業(yè)循環(huán)試驗條件復雜且難于再現(xiàn)。

本文件的專用試驗規(guī)程規(guī)定了具體的試驗程序，可在動態(tài)試驗條件下，以可重復的工況測定A計

權(quán)聲功率級環(huán)境發(fā)射噪聲和A計權(quán)時間平均聲壓級司機位置發(fā)射噪聲。

本文件根據(jù)裝載機的功能和主要作業(yè)工況與噪聲之間關(guān)系的研究結(jié)果，除行駛工況和定置作業(yè)循

環(huán)工況外，增加了前進行駛聯(lián)合作業(yè)循環(huán)工況，按照噪聲惡劣工況優(yōu)先原則，多工況并行，進行噪聲

評價。

純電動裝載機動態(tài)噪聲試驗方法

1范圍

本文件規(guī)定了純電動輪胎式裝載機（以下簡稱“裝載機”）測量動態(tài)噪聲時所需的儀器與測量準確

度、試驗環(huán)境、試驗準備、測試結(jié)果的確定、測試報告的編寫等方面的內(nèi)容，描述了在動態(tài)試驗條件下，

A計權(quán)聲功率級環(huán)境發(fā)射噪聲和A計權(quán)時間平均聲壓級司機位置發(fā)射噪聲的測定方法，確立了測量

程序。
