摘　　要：重型车辆作为物流运输体系中不可或缺的基石,其广泛应用在带来经济效益的同时,也引发了日益严峻的噪声污染问题。噪声污染已成为举世瞩目的一大公害。城市噪声主要来源于汽车交通噪声,它是目前城市最主要的污染源之一,也是评估汽车环保性能的重要指标。汽车噪声严重影响人们的日常生活和休息,严重时甚至危害人们的身体健康。因而,本文旨在全面分析多工况条件下重型车辆的噪声特性,探讨不同工况对车辆噪声水平的影响,并提出有效的降噪策略,为重型车辆噪声控制提供科学依据和技术支持。As an indispensable cornerstone of the logistics and transportation system,the wide application of heavy-duty vehicles not only brings economic benefi ts,but also causes increasingly serious noise pollution problems.Noise pollution has become a major public nuisance that has attracted worldwide attention.Urban noise mainly comes from automobile traffi c noise,which is one of the most important pollution sources in the city at present,and it is also an important indicator to evaluate the environmental performance of automobiles.Car noise seriously aff ects people's daily life and rest,and even endangers people's health in serious cases.Therefore,the purpose of this paper is to comprehensively analyze the noise characteristics of heavy-duty vehicles under multi-working conditions,discuss the infl uence of diff erent working conditions on the noise level of vehicles,and propose eff ective noise reduction strategies to provide scientifi c basis and technical support for noise control of heavy-duty vehicles.
