摘要
本文以大采高工作面中应用的ZY29000/45/100D型液压支架的掩护梁结构为研究对象,利用SolidWorks和ANSYS软件建立模拟仿真模型。分析发现垫块、主筋板和上盖板交汇部位出现了应力集中现象,且最大应力超过了材料的许用应力,存在安全隐患。采用将4块主筋板厚度增加10mm的方式对结构进行优化改进,并再次模拟仿真优化后的掩护梁,发现最大应力降低到了许用应力范围内。根据优化方案加工得到了实物,并在工业中实践了6个月,发现达到了预期效果,使用寿命预计可以延长25%以上。
This paper taking the cover beam structure of ZY29000/45/100D hydraulic support applied in large mining height working faces as the research object,a simulation model was established using SolidWorks and ANSYS software.Analysis found that stress concentration occurred at the intersection of the cushion block,main reinforcement plate,and upper cover plate,and the maximum stress exceeded the allowable stress of the material,posing a safety hazard.By increasing the thickness of the four main reinforcement plates by 10 mm,the structure was optimized and improved.The optimized cover beam was simulated again,and it was found that the maximum stress was reduced to within the allowable stress range.According to the optimization plan,the actual product was processed and practiced in industry for 6 months.It was found that the expected effect was achieved,and the service life is expected to be extended by more than 25%.
