旋挖钻机回转平台主体结构改进及优化

Improvement and Optimization of the Main Structure of Rotary Drilling Rig

现行的某型号旋挖钻机的回转平台为箱型结构，本文将其改制为工字梁结构。然后借助有限元仿真软件ANSYS Workbench对两种转台结构进行有限元仿真，对比分析，选择较好的结构，然后对这种结构进行优化．使结构在满足力学性能的前提下，尽量减轻自重，减少原材料的使用。

The box type structure of a type of rotary drilling rig platform is the restructured to Gongziliang structure in this paper. The finite element simulation is carried out in two turntable structure by means of finite element simulation software ANSYS Workbench. After comparative analysis, good structure is choosed, and then the structure is optimized, under the precondition of satisfying the mechanical properties, it is to reduce the weight and the using of raw materials.
