摘要
汽车前照灯作为汽车零件的一部分,为汽车美观性与夜间行驶安全性提供了保障。汽车前照灯力学性能设计的优劣对前照灯的寿命以及各行驶工况是否会发生振动失效具有重大影响。本文借助手持式三维扫描仪、三维建模软件CATIA对长安1.5T紧凑型SUV CS75前照灯进行逆向建模,并通过有限元分析软件ANSYS对前照灯在各行驶工况下受到激励的振动模态进行分析,所得结果对研究前照灯动力学性能,对其结构改良和优化具有重要意义。

Abstract
As part of the car's parts, the car headlights provide a guarantee for the aesthetics of the car and the safety of night driving. The advantages and disadvantages of the mechanical performance design of automobile headlamps have a significant impact on the life of the headlamps and whether the vibration conditions will occur in all driving conditions. In this paper, the Changan 1.5T compact SUV CS75 headlamp is reverse modeled by hand-held 3D scanner and 3D modeling software CATIA, and the vibration of the headlights under the driving conditions is simulated by the finite element analysis software ANSYS. The modal analysis is carried out, and the results obtained are important for studying the dynamic performance of the headlamps and improving their structure and optimization.
