摘　　要：以履带式可伸缩转运机举升机构为研究对象,在已有举升机构设计理论的基础上,本文设计一种新型举升机构,考虑在具体工况中各点始末位置及最大举升角度的几何关系,对机构的结构尺寸进行设计计算。基于现实工况特殊的强度要求,对机构的各部位进行受力分析,并借助有限元分析软ANSYS Workbench模拟了三角臂与摆动装置的受力情况,对结构强度进行校核,对三角臂结构进行了拓扑优化。结果表明,此举升结构具有可行性,并为其他机械举升机构优化设计提供理论依据和指导作用。Taking the lifting mechanism of the crawler-type retractable transfer machine as the research object,a new type of lifting mechanism is designed in this paper,The starting and ending positions of each point and the maximum lifting angle in specific working conditions.The geometric relationship is used to design and calculate the structural dimensions of the mechanism.Based on the special strength requirements of the actual working conditions are considered in the design,the force analysis of each part of the mechanism is carried out,and the force of the triangular arm and the swing device is simulated with the finite element analysis software ANSYS Workbench,The structural strength is checked.And the topology optimization of triangular arm structure is carried out.The results show that this lifting structure is feasible,which provides theoretical basis and guidance for the optimal design of other mechanical lifting devices.
