摘要
就汽车开发阶段的高频振动噪声预测进行了研究,介绍了建立汽车振动噪声统计能量分析模型的方法和过程,并对两种车型驾驶舱子系统的噪声特性进行了预测和对比。
The prediction method of high -frequency vibration noise is mainly analy zed when the vehicle is at devel-opment stage.By applying statistic al energy analysis(SEA)theory and vehicle vibration theory,the modeling method and process are introduced.As an exampl e,the noise characteristics of two c ar' s cabins are predicted and compared,the calcu-lating results provide a reference t o redesign the vehicle body in order t o better the noise characteristic of the vehicle.
