| 摘 要： | 以A型地铁车辆为研究对象,利用SYSNOISE软件计算了车内声场的声学模态。结果表明,车内声场的各阶模态形状基本上呈前后、左右和上下方向对称分布,车内声场共鸣频率和模态形状主要由其几何形状决定。

| Abstract: | The A type metro vehicles are used as the research object,and acoustic mode of sound field inside vehicles are calculated with the SYSNOISE software.The result shows that the modal shapes of various stages of sound field inside vehicles are nearly symmetrically distributed in the directions of front and rear,right and left,up and down.The resonance frequency and modal shape of sould field inside vehicle are determined mainly by the geometrical shape. |
