微型货车车门垂直刚度仿真与分析
Simulation and Analysis of Vertical Stiffness of Minivan Door
摘要: 本文利用三维设计软件UG建立了某微型货车车门系统，使用有限元软件Hypermesh对三维模型进行有限元建模处理，对车门系统进行自由模态分析和静态刚度仿真模拟。仿真结果显示车门自由模态分析的一阶振型在正常范围内，但车门的垂直刚度偏低。对车门的铰链加强板等部件改进后使加载位移降低11.4%，低于目标值，满足了设计要求。
Abstract:
In this paper, the door system of a minivan is established by using the 3D design software UG. The 3D model is modeled by using the finite element software Hypermesh, and the free mode analysis and static stiffness simulation of the door system are carried out. The simulation results show that the first mode shape of the door is within the normal range, but the vertical stiffness of the door is low. The load displacement is reduced by 11.4%, which is lower than the target value, and meets the design requirements.
