基于ANSYS的回转台车架的有限元分析与结构改进

Abstract

堆取料机的回转机构是整机执行悬臂回转动作的重要组成部分，作用是带动斗轮机构、俯仰机构以及配重等上部结构在水平面内转动，而回转支承是回转机构的核心部分。本文利用ANSYS对回转台车架进行有限元静力分析，得出总变形图和等效应力图。通过有限元静力分析结果与理论计算比较，验证了结构满足使用要求。同时，本文还提出了对回转台车架的结构改进方案，为回转机构设计提供了必要的参考。 The slewing mechanism of stacker reclaimer is an important part of the cantilever rotary action. The role is to drive the superstructure part of the bucket wheel, luffing mechanism as well as with weight in the horizontal plane. The slewing ring is the core part of slewing mechanism. The statical (Finite Element Analysis) FEA for slewing bogie based on ANSYS shows the total deformation diagram and the equivalent stress diagram. The comparison between the statical FEA results and the theoretical calculation results can confirm that the structure satisfies the operation requirements. Meanwhile, this paper also presents structural improvement for the slewing bogie which provides the necessary basis for the slewing mechanism design.
