摘　　要：为降低某牵引车低阻进气系统对驾驶室内噪声的影响,基于模态仿真分析和台架模态测试,建立进气系统模态仿真模型,对影响驾驶室内噪声的进气系统主要阶次噪声进行定位、定频,并利用该模型研究了进气系统进气道总成、空气滤清器总成和底座总成噪声的特点、相应降噪措施及效果,通过精准控制上述主要总成的模态并进行优化设计,有效降低了驾驶室内噪声。To reduce the influence of the tractor low-resistance intake system on the cab interior noise,a modal simulation model of the intake system is established,and the main modal noise frequencies that affect the interior noise are located and defined.The paper studies the characteristics,noise reduction measures of intake system air passage assembly,air filter assembly and base assembly,along with thecorresponding noise reduction measures and effects.The modal characteristics of the above assemblies are precisely controlled and optimized,which effectively reducing the overall interior noise of the vehicle.
