摘要
利用三维建模软件I-DEAS和非线性有限元分析软件ANSYS/LS-DYNA,建立包含冲击块和铝合金轮毂模型在内的非线性有限元模型,并对有限元模型进行适当简化。采用LS-DYNA显式算法,对轮毂模型从3个不同部位进行冲击模拟,预测危险点出现的位置,选用某型号轮毂利用实际冲击试验进行验证。结果表明,该有限元模型的建立及简化方法合理,模拟结果与试验结果能够很好的吻合,该型号轮毂强度符合13°冲击测试标准,为轮毂设计人员在前期开发阶段提供了有效的参考。
Three dimensional modeling software I-DEAS and nonlinear finite element analysis software ANSYS/LS -DYNA were used to build nonlinear finite element model which includes impact block and aluminum alloy wheel, and the finite element model was proper simplified. LS-DYNA explicit algorithm was used to conduct the impact simulation for three different location of the wheel, thus to predict the dangerous points might occur. A certain type of aluminum alloy wheel was employed to study the practical 13° impact test. The simulation results showed that the methods of building and simplifying the finite element model were rational, and that was in good agreement with the impact test results. The strength of the certain type of aluminum alloy wheel satisfied the standard of 13° impact test. The approach presented in this paper provided effective reference to wheel designers at the early development stage.
