摘　　要：分析了拖拉机通过噪声的成因主要是发动机噪声、风扇噪声及传动系噪声,经试验分析得到风扇及发动机噪声对拖拉机通过噪声影响较大,给出了降低每个噪声源的一些措施,并分析了现有拖拉机后期降噪方案的优劣。In this paper,the causes of tractor pass-by noise are mainly engine noise,fan noise and transmission noise,through test and analysis,it is found that the noise of fan and engine has great influence on tractor pass-by noise,some measures to reduce each noise source are given,and analyzed the advantages and disadvantages of the existing tractor late noise reduction scheme.
