The Design and the Topological Optimization of the Tracked Triangle Wheel’s Basic Frame
In this paper, the stress and strain of the tracked triangle wheel’s original basic frame which is used on shovel loader were analyzed in AnsysWorkbench. And topological optimization method was then used to optimize the basic frame so as to find out its best bearing structure, after which the original basic frame was improved and designed for the second time in the solidworks environment. And then, the stress and strain of the basic frame’s new structure were analyzed again. In the end, a comparison was carried out between the finite element analyze results before and after the topological optimization. According to the comparison, the weight of the basic frame is reduced by 22.5% while the stress and strain nearly keep the same.
