摘　　要：针对微型电动游览车匀速直线行驶和一车轮瞬时悬空两种工况,分析了底盘变形和应力分布。在动态分析中应用模态分析方法,计算得出了底盘自由状态下的10阶频率和对应的振型及固有频率,给出了避免车体产生共振和噪声的方法及途径。The deformation and stress distribution of a mini-electrical tourist car chassis was analyzed under two conditions which were running with uniform velocity, and one wheel instantaneously leaving the road surface. By the modal analysis method in dynamic analysis, the first ten natural frequencies of the chassis in free state and the corresponding mode shape were calculated, and the ways to avoid the body resonance and noise were given.
