摘要
利用RecurDyn对铰接车进行了动力学仿真,计算出了整车原地转向时车轮连接端的受力。在此基础上,通过三维软件SolidWorks建立了摆臂机构的模型,利用HyperWorks对该机构壳体进行OptiStruct结构有限元分析,得到其各节点的应力应变云图及变形图,发现车辆转向载荷作用下,该外壳结构能达到强度要求而不能达到刚度要求。通过对原结构进行加强与优化,使设计满足铰接车各种工况下强度、刚度要求,为车辆平稳行驶提供保障。
With the dynamieal simulation software ReeurDyn, dynamics simulation is conducted to the articulated vehicle, the forces between vehicle wheels and connecting shafts are got when the whole vehicle turns fixedly. On this basis, using Solid- Works modeling software, tile finite element model is built and then a strength calculation and finite element simulation analysis of mechanism shells is conducted by OptiStruct method in HyperWorks. From results of the stress distribution and parts deforma- tion, it is discovered that swing arm mechanism satisfies strength requirements while dissatisfies stiffness requirements. By strengthening and optimizing the original structure, the strength and stillness requirements are met. It also provides guarantee for smooth running of the vehicle.
