基于有限元理论的折叠式防突钻机设计及仿真OA

To address the issues of the large overall structural dimensions,insufficient operational flexibility,and low work efficiency in existing outburst prevention drill rigs,a foldable outburst prevention drill rig was designed based on an analysis of its structure and working principle.Through structural optimization of the feeding mechanism and the slewing mechanism,a slewing device was added at the base of the feeding mechanism to enable the folding function of the drill rig.Static and dynamic analyses of the complete machine were conducted using ANSYS Workbench.The results showed that the strength and vibration characteristics of the key components met the design requirements,the overall structural dimensions of the rig were significantly reduced,and both the flexibility of drilling operations and work efficiency were effectively improved.
