| 摘 要： | 除了在燃烧激振力和机械激振力的产生根源上采取措施之外，在此类激振力的传递途径上表面辐射噪声的效率方面采取措施，同样可以达到有效控制发动机噪声的目的。基于此种想法，对发动机气门室罩进行建模并做有限元分析，并且与发动机试验相结合，最终得出影响系统总体响应的位置因素，从而为改进该位置提供了理论和实际的双重依据。

| Abstract: | Besides measures aiming at generating sources of combustion exciting forces and mechanic exciting forces,measures aiming at transferring paths and noise surface radiation can also be applied to effectively control engine noises.Based on the idea,the finite element model of the enine valve cover are created and analyzed,and synthesizing en-gine tests,position factors effecting entire system response are found out finally.This offers the theoretical and practical du-al basis for position improvement.Topic words :Valve cover,The finit element method,Noise |
