| 摘 要： | 本次研发的宽体车总质量为40t,是在总质量60t级平台产品的基础上向下衍生而来的。应用三维造型软件建立了矿用自卸车实体几何模型,并对关键结构——车架给出了应力分析时的模型简化方法,根据整车的装配关系和车架的受力特点确定了车架强度有限元分析的边界条件,在此基础上建立了包括车桥、悬挂和车厢在内的整车有限元模型,依据矿用车的典型受力重点选取满载静止或平稳行驶、扭转组合和侧倾举升作业作为分析工况,应用ANSYS软件求解得到各工况下车架的应力大小和应力分布规律。为验证整车的性能,在华润水泥南宁公司矿山对样车进行了为期3个月的性能试验,并对该矿车进行了全面检验,为下一步优化设计提供依据。

| Abstract: | The total mass of the wide-body car for this research is 40 t,a derivative based on the 60 t series.It applies three-dimensional moulding software to building the mine tipper solid geometry model,provides the key structure,car frame,a model reduction method in the stress analysis.Boundary condition of the frame strength finite element analysis is decided by the vehicle assembly and the car frame stress characteristics.On this basis,the vehicle finite element model,including the vehicle axle,the suspension a... |
