摘要
传递路径分析是分析车辆噪声的重要手段,运行工况传递路径分析是对传统传递路径分析方法的改进。首先建立车内噪声的运行传递路径分析模型,介绍传递矩阵的求解算法。针对某乘用车车内噪声问题,进行运行工况下传递路径分析,获得各个声源对车内噪声的贡献率,为制定合理的车内降噪方案提供重要支持。
Transfer path analysis is an important tool to analyze vehicle＇ s interior noise. Operational transfer path analysis is an improvement of the traditional transfer analysis method. At first, the model for operational transfer path analysis of vehicle＇ s interior noise was built and the algorithm of matrix transfer method was discussed. Then, the method was applied to a passenger car to analyze the operational transfer path of the interior noise. Finally, contribution of each noise source was analyzed. This work provides a significant support for vehicle＇s interior noise control.
