悬臂掘进机一体化施工平台优化设计

Optimization Design on Integrated Construction Platform of Boom-type Roadheader

悬臂掘进机一体化施工平台是一种适应复杂围岩条件下,实现拱形金属支架支护,且与掘进机一体的挑梁和踩踏机构。文章利用Pro/ENGINEER Mechanica(Pro/Em)软件对初始设计进行了有限元分析,分别求出挑梁和载人两种工况下最大应力和最大变形的承受部位以及应力和变形数值大小,验证了初始设计的可靠性。另外,在有限元分析的基础上对平台材料进行了优化选择,既保证支护作业的安全,又实现节省材料和减少能耗的目的。

Integrated construction platform of boom - type, an outrigger and standing mechanism integrated with roadheader, could adapt conditions of complex surrounding rock, realizing supporting with metallic support. The finite element analysis on the initial design was conducted with Pro/ENGINEER Mechanica software. The maximum stress zone and the maximum deformation zone under the superimposed load and the manned conditions were determined, and the values were obtained. The results of finite element analysis verified the reliability of the initial design. The material of platform was optimized based on the finite element analysis results. The design ensured the supporting work safety, but saved materials and energy consumption.
