| 摘 要： | 运用Hypermesh软件建立了某型高速列车有限元模型，选定内侧地板、侧墙和车顶作为研究对象，分析了承载结构厚度尺寸的变化对车体一阶垂向弯曲、菱形和扭转变形固有频率的影响。结果表明，车顶厚度的变化对车体模态频率的影响最大，在车体设计时可通过修改车顶的参数来改进车体的模态特性。

| Abstract: | The finite element of the car-body has been built by means of Hypermesh. Select inside-floor, sidewall and roof as research target, analyse the effects of Load Bearing Structure＇s thickness on the Car-body＇s vertical bending, rhombic and torsion＇s natural frequency. Find out roof＇s thickness is the most significant factor that will influence car-body＇s modal characteristics, thus, by changing roof＇s thickness can optimize car-body＇s modal properties. |
