This paper studyies the method of controlling SC6360B's accelerated vehicle Exterior noise. First, the main noise is found, which is from engine compartment and from exhaust noise by the identification of vehicle noise resource. Second, this paper carris out the farther noise identification experiment on engine and the insert-loss experiment on the exhaust gas muffler. In the end, the authors make sure that the noise is mainly infected by direct leaked noise from engine compartment, radiation-noise caused by the vibration of engine accessories and loud exhaust noise because the muffler has dficient elimination . The corresponding methods has been adopted according to the analysis. Through the test, the noise is lowered 2.5 dBA than it was and reach the new requirement.

为了降低SC6360B车外加速噪声,对该车的噪声控制措施进行了综合性研究。采用声强测量法对整车进行了噪声源识别,确定该车发动机舱泄漏的噪声及排气噪声是车外噪声的主要来源。并依据实验结果对发动机的进一步的声源识别以及对排气噪声的插入损失分析实验。根据实验研究结果及有限元数值分析,最终确定发动机舱噪声的直接泄漏、油底壳罩等附件的振动辐射噪声以及原消声器的消声能力不足是造成车外噪声的主要成因。从而相应提出了对发动机舱隔声降噪、改善油底壳等附件的结构及改进原消声器的综合控制方案。经实验验证, 改进后的车外加速噪声降低了2. 5dBA,达到了新的国家标准。
