摘　　要：随着汽车工业的蓬勃发展,汽车噪声严重影响着人们的日常生活,汽车产生的噪声包括发动机噪声、传动系统噪声、风扇噪声以及排气系统噪声,其中发动机噪声是汽车噪声的主要来源,引起国内外学者的广泛研究。文章运用灰色关联度法对发动机噪声影响因素(转速、高度、水平距离)进行计算,得出相应关联系数与关联度,由此得出发动机噪声影响因素的主次程度,并针对主要影响因素进行降噪方法研究。Along with the rapid development of the auto industry,the noise of the car has seriously influenced people's daily life.Automotive noise consists of engine noise,transmission system noise,fan noise and exhaust system noise,among which engine noise is the main source of automobile noise,causing extensive research by domestic and foreign scholars.In this study,the grey relational degree method is used to calculate the influencing factors of engine noise(speed,height,and horizontal distance),and the corresponding correlation coefficient and correlation degree are obtained,thus the primary and secondary degree of influencing factors of engine noise is obtained.Furthermore,the method of reducing noise is researched for the major influencing factors.
