以某型号的汽车高位刹车灯为例，在CATIA软件中建立其三维模型，并对安装支架进行静力学计算和模态分析。静力学计算结果表明该灯的安装支架受力相对均匀，该结构的最大位移和应力均满足设计要求；模态分析结果表明该灯的前两阶固有频率达到了设计要求，该系统具有良好的动态特性。

The article takes a type of high -level brake lamp for a car as an example ,establishes the 3D model in CATIA software ,and the mounting bracket for statics calculation and modal analysis .The statics calculation results indicate that the mounting bracket of the lamp ’ forces are relatively average , this architecture's biggest displacement and the stress both satisfy the design requirements .T he modal analysis results indicate that the lamp of the first two natural frequencies reached the design require-ments ,so the system has the good dynamic performance .
