摘要
车架是汽车重要的基础部件之一,须具有足够的强度和刚度。应用HYPERWORKS建立了车架的有限元模型,根据对该模型进行的受力分析,施加了合理的约束条件和载荷,对车架最为典型的四种工况进行了静力学研究,并根据车架的应力应变云图,预测出车架的薄弱部位,提出了前瞻性的建议,为车架的优化设计和车架结构的改进提供了非常重要的理论依据。
Frame is one of automobile＇s most important basic component,which needs sufficient strength and stiffness.A finite element model of frame was established through HYPERWORKS software,reasonable constraint conditions and load was imposed on the finite element model according to the mechanical analysis,and the most significant four operating conditions of the frame was analyzed through static method.The stress-strain contour of the frame was obtained;Finally,the weak parts of the frame was predicted,and several predictable suggestions were opposed,which provides important theory foundation for the optimizing design and structure improvement of the frame.
