摘　　要：进气系统噪声是整车的噪声源之一,其噪声的控制和优化是提高整车NVH品质的重要工作之一,一直困扰着发动机进气系统的设计过程。引入CFD分析结合试验的方法,可以准确快速地选择降低噪声的方案,对提高进气系统设计效率、减低设计成本具有明显的优势。The noise of the air intake system is one of the noise source on the vehicle, and the control and optimization of the noise is one of the important work to improve the vehicle NVH quality, which has plagued the design process of engine air intake system. In order to choose the plan to reduce noise accurately and quickly, the methods of CFD analysis and test has been introduced. It has obvious advantages on improving the design efficiency and reducing the design cost of the air intake system.
