| 摘 要： | 汽车发动机进排气系统的噪声在发动机总噪声中占有重要分量，因此需要积极采取降噪措施。通过建立发动机进排气系统的理论模型，利用声波有限元分析法对发动机进排气系统的噪声特性作出预测，并将实际计算结果与实测值进行比较，结果表明声波有限元分析法能有效地预测不同结构的进排气系统的噪声特性。

| Abstract: | The car noise admission and exhaust system of the engine is a very important problem, therefore we must adopt innovative technic to reduce noise .By establishing the theories model of the admission system and exhaust system of the engine, and making use of the voice wave finity element method to predict the characteristic of noise actuality,then we will compare with the actual calculation and measured result.The results show that the finity element method is effective in predicting the noise characteristics of engine. |
