重型卡车重要噪声源分析与降噪方法研究

介绍了国内外重型卡车通过噪声限值的发展过程,讨论了国内重型卡车通过噪声主要声源及主要降噪措施,并通过具体工程实例对分析结果进行了验证,试验证明本文所采取的重型汽车通过噪声降噪措施是有效的,为国内重型卡车的降噪提供了技术方案,最后建议国内重型卡车应在开发初期注重噪声性能的开发.

The Study on Main Noise Sources Analysis and Noise Reduction Method of Heavy Truck

This paper introduces the process of pass by noise of heavy truck Inland or aboard,then we mainly discusses the noise source of domestic heavy trucks and the methods of reduction the noise.Through the specific engineering example,the main methods were verified.The result tells us that the methods are effective and there are the mainly measures for coutrolling the noise of heavy trucks.At last,we suggested that engineers should pay attation to the noise performance of trucks at the development initial.
