摘　　要：基于SolidWorks三维建模Part模块以及Simulation仿真分析模块,结合工程实际建立了煤矿用多功能巷道修复机(以下简称巷道修复机)挖斗仿真分析模型,通过挖斗仿真分析与结构优化确定了挖斗最大挖掘力载荷。针对不同工况,对柔性化处理的挖斗进行了加载与仿真,找出了挖斗的薄弱环节。仿真分析发现,适当增加挖斗侧刃板长度、减小底板弧形角、在侧刃板与底板间增加U型筋板以提高焊接强度对挖斗整体强度和刚度的提高十分有益,同时在巷道修复机刷帮前进行充分的破碎作业有助于提高挖斗的使用寿命。Based on Part module of SolidWorks 3D modeling and analysis module of Simulation software, combined with engineering practices, the author built a simulation analysis model of excavator bucket of multifunctional roadway repairing machine for coal mine, and then calculated out the maximum digging force of the excavator bucket through excavator bucket simulation analysis and structure optimization. Aiming at different operation conditions, the flexible processed excavator bucket was loaded and simulated with different conditions, and the weak links were found. The simulation results showed that it was very useful to improve the overall strength and stiffness of excavator bucket by increasing bucket side blade plate length, reducing the bottom arc angle or improving the welding strength by adding a U-shaped steel reinforcing plate between the side blade plate and the bottom plate, and it was also helpful to improve the service life of the excavator bucket by fully crushing surrounding rocks before side cleaning .
