悬臂掘进机一体化施工平台优化设计

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。

North China Institute of Science and Technology, Beijing China,101601;3.Linnancang Coal Mine of Kailuan Group，Tangshan China,064106) AbstractIntegrated construction platform is rationally matched with the boom roadheader under the complex surrounding conditions, which have a mechanical beam building, and provide a safety standing basis for the construction of the frame shield support. We use Pro/ENGINEER Mechanica software to carry on finite element analysis for the initial design. The maximum stress zone and the maximum deformation zone and the values are achieved under the superimposed load and the manned conditions. The results of finite element analysis can verify the reliability of the initial design. The material of platform is optimized based on the finite element analysis results. Using modern design method can not only ensure the supporting work safety, but save materials and reduce the energy consumption.
