利用ANSYS软件对移动式垃圾转运站箱体结构建立了参数化几何模型和有限元分析模型,采用接触副合理解决了推头、垃圾、箱体间的接触和轴销连接问题。在此基础上进行了压缩进程、上车进程、满载颠簸、刹车行驶、卸料顶起和翻斗作业最大反力等11种危险工况下的约束、加载和结构有限元分析计算,得出各工况下结构的应力分布和最大应力。采用ANSYS与导重法相结合的结构优化方法对移动式垃圾转运站箱体结构进行了优化设计,在满足结构强度要求的前提下,使箱体结构的总重量减少了20.2%。
The ANSYS software was used to set up parametric geometric model and finite element analysis model for mobile refuse transfer station box structure. The contact problem of push head, rubbish, box body and shaft pin connection was solved by using contact pair. On this basis, the constraints, loading and structural finite element analysis of the 11 kinds of dangerous conditions, such as compression process, on the car process, full bumpy, brake driving, dump jacking and dumping maximum reaction force were obtained, Structure stress distribution and maximum stress under operating conditions. The structural optimization of mobile refuse transfer station is optimized by the structural optimization method combining ANSYS and guided-gravity method. The total weight of the box structure is reduced by 20.2% under the premise of meeting the structural strength requirements.
