| 摘 要： | 在新车身设计阶段，由于汽车内部诸多因素的不确定，用有限元计算声腔模态时对声腔模型进行了简化处理。对比了有无座椅和仪表盘挡板的车内声学模态结果，用边界元法进行了车内结构辐射声压计算和声贡献量分析，对改进车内噪声有一定参考。

| Abstract: | The inner acoustic modes of a car are computed in the initial design stage with a simpli-fied finite element model. Results of the acoustic modes with/without seats, and with/without instrument panels are compared. Radiating sound pressure computation and sound contribution analysis in the car are carried out by means of the boundary element method. This work is of reference for the improvement of interior noise condition of vehecles. |
