汽车车内中高频噪声模拟仿真分析
Simulation and Analysis on Automotive Mid-High Frequency Noise
摘要
Abstract
An SEA model of a passenger car is established to predict the mid-high frequency noise in cab.The modal density,damping loss factor and coupling loss factor are obtained by combining the measure of calculation and test.Then acoustic radiation of engine cabin and vibration of power assembly mounting system are measured by engine neutral gear 5 000 r/min test.By the contrast simulation with experiment result of cab noise,SEA model is validated.Finally,mid-high frequency noise simulation with chassis noise input and sound pressure response analysis of cab are accomplished.关键词
