摘要:
基于有限元分析法,以某SUV为研究对象,建立了其有限元模型,对后保险杠中心和车角碰撞过程进行了模拟,通过分析其吸能特性,评价了后保险杠的碰撞性能,然后根据法规要求,对后部100%和40%重叠低速碰撞进行了仿真,分析了碰撞过程各部件的变形、应力分布及能量变化等,验证了设计的合理性,为结构的进一步优化提供了依据,该方法为研究整车后部碰撞提供了新的思路,对深入研究后保险杠、整车碰撞仿真及实车碰撞试验具有重要的参考价值.
Abstract:
The finite element model which takes a SUV as the object is established based on finite element a-nalysis,and this paper simulates the center and angle collision process of the rear bumper. It evaluates the per-formance of the rear bumper collision by analyzing the energy absorption characteristics. According to the laws and regulations, this paper simulates the 100% and 40% overlap of the rear part low-speed collision and ana-lyzes the collision deformation of every part, stress distribution and energy change, In the end,it verifies the rationality of the design. The results provide a basis for the further optimization of the structure and offer a new idea for the vehicle collision,and they are of great reference value for further study of the rear bumper, the ve-hicle collision simulation and real vehicle crash test.
