摘要
该文主要探究斗轮堆取料机俯仰结构有限元模型的构建过程、静力分析和优化设计。该文首先使用UG软件构建俯仰结构模型,然后使用HyperMesh软件对该模型进行几何清理与网格划分。在此基础上,设计俯仰结构有限元分析方案,在施加载荷与边界处理后展开静力分析。结果表明,斗轮堆取料机俯仰结构的等效应力远低于容许应力,结构强度达标。随后选取俯仰结构的前臂架,Ansys软件中的Design Explorer模块展开优化设计,将重量作为优化目标。在不改变前臂架最大等效应力的前提下,前臂架的重量从原来的21767 kg变为18240 kg,重量减幅达到16.2%,优化效果明显。
This paper mainly explores the construction process,static analysis and optimization design of the pitching structure finite element model of bucket wheel stacker and reclaimer.In this paper,the pitching structure model is constructed by using UG software,and then the model is geometrically cleaned and meshed by HyperMesh software.On this basis,the finite element analysis scheme of pitching structure is designed,and the static analysis is carried out after applying load and boundary treatment.The results show that the equivalent stress of the pitching structure of the bucket wheel stacker and reclaimer is much lower than the allowable stress,and the structural strength is up to the standard.Then the forearm of the pitching structure is selected,and the Design Explorer module in Ansys software launches the optimization design,taking the weight as the optimization goal.Without changing the maximum equivalent stress of the forearm,the weight of the forearm is changed from the original 21767 to 18240 kg,and the weight is reduced by 16.2%,hence the obvious optimization effect.
