进气系统噪声改进

Noise Optimization of Air Intake System

针对某皮卡车噪声评估过程中加速噪声水平没有达到目标样车的水的问题进行研究。文章根据该车整车及进气系统噪声测试结果改进空滤器进气管及根据赫姆霍兹谐振消音器原理设计合适谐振腔,降低进气噪声。

Noise assessment process of a pickup truck show that acceleration noise level did not reach the target prototype.According to the noise test results of vehicle and air intake system to improve the air filter inlet pipe and design suitableresonant cavity based on the principle of Helmholtz resonator muffler, and reduce the intake noise.
