| 摘 要： | 在工作过程中,煤矿用履带式巷道修复机工作机构容易受到较大的冲击力,使薄弱部位产生变形甚至断裂.对修复机工作机构在挖掘工况下进行受力分析,建立煤矿用履带式巷道修复机的动臂和斗杆的三维模型,并利用有限元分析软件进行仿真分析.结果表明:煤矿用履带式巷道修复机动臂的最大应力为291.730MPa,最大位移为0.289 000mm,斗杆的最大应力为102.660 000MPa,最大位移为0.096 221mm,均满足强度和刚度要求,验证了结构设计的合理性.

| Abstract: | The working mechanism of colliery crawler roadway repair machines is easily impacted during working process to produce weak position deformation even fracture. Based on the loading analysis, the 3D models of boom and bucket rod are established for simulation analysis via finite element software. As such, it is found that the maximum stress and displacement of boom are 291. 730 MPa and 0. 289 000 ram, respectively, whereas the maximum stress and displacement of bucket rod are 102. 660 000 MPa and 0. 096 221 ram, respectively. Accordingly, the strength and stiffness requirements are satisfied. Therein, the structural design rationale is verified to provid a basis for further optimization on working mechanism. |
