摘要
以TJ7101U轿车为研究对象,介绍了用于汽车碰撞模拟计算的非线性有限元法基本理论与算法,建立了夏利轿车的整车碰撞分析有限元模型,并应用非线性有限元模拟技术对该模型进行了车速为50km/h的轿车与固定刚性壁障正面碰撞的仿真计算。与已完成的该车型实车碰撞实验结果进行了对比分析,仿真计算的变形结果和实验数据吻合较好,验证了所建立的有限元模型的正确性。
The fundamental theory and arithmetic of non-linear finite element method for vehicle crash simulation calculation are introduced based on an example of Xiali TJ7101U car, building finite element model of complete vehicle crash analysis. Meanwhile, simulation calculation is carried out for a frontal crash with 100% overlap rigid barrier at the speed of 50 km/h using non-linear finite element. Deformation results of simulation calculation are in accordance with test data compared with real crash, showing that finite element model is correct.
