基于CAE和传递路径分析的某车加速工况下车内噪声研究
Study of the Automotive Interior Noise in the Acceleration Condition Based on CAE and Transfer Path Analysis
摘要
Abstract
In order to control the interior noise in the acceleration condition, the paper focused on analyzing of the position of driver's right ear noise response in the frequency range of 20~200 Hz through the CAE analysis technique combined with the transfer path analysis method, and calculating the position of driver's right ear and right rear passenger left ear noise pressure excited by different transmission path.After the test investigation, we find that mount interference is appeared when the engine speed is 4 200 r/min to 4 700 r/min because of the large excitation force, therefore, the target response point pressure is too large.关键词
