斗轮堆取料机俯仰结构的有限元分析及优化设计OA

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 21 767 to 18 240 kg,and the weight is reduced by 16.2%,hence the obvious optimization effect.
