摘要
以某客车车架结构为研究对象,利用Hyperworks软件建立车架有限元模型,根据对此模型的受力情况分析,施加了模拟的约束和载荷条件,计算了四种不同典型工况下此车架的强度和刚度。结果显示,急转弯和紧急制动工况的应力满足要求,但弯曲和扭转工况下的最大应力略大于材料的屈服强度。最后,根据计算结果预测出车架的薄弱处并提出合理建议,为车架的结构优化改进提供理论依据。
Taking a bus frame structure as the research object,the finite element model of the frame is established by Hyperworks software.The simulated constraints and load conditions are applied according to the force analysis of the model,and the strength and stiffness of the frame under four different typical working conditions are calculated and analyzed.According to the calculation results,the weak points of the frame are predicted and reasonable suggestions are put forward,which provides theoretical basis for the optimization and improvement of this bus frame.
