回复反射器鼓包值有限元模拟

Finite Element Analysis of Retro-reflector

汽车回复反射器在退火去应力工艺过程中由于材料发生塑性变形产生鼓包。现以一款汽车回复反射器为研究对象,利用有限元软件NX Nastran建立灯具有限元模型,对其进行非线性仿真分析。利用三坐标测量灯具实际鼓包值来验证仿真分析的可行性,为灯具前期结构设计以及后期试验验证提供参考。

The bulging phenomenon occurs in retro-reflector due to the plastic deformation of the material during the stress annealing process.This paper takes a retro-reflector as object of study,uses the finite element software NX Nastran to establish a car retro-reflector finite element model for the nonlinear analysis and uses three coordinate measuring actual bulge value to verify the feasibility of the simulation analysis.
