摘要
针对关节轴承实际生产中挤压力过大、衬垫挤压不均匀等问题,以YSG502S12轴承为研究对象,应用有限元分析软件LSDYNA,对轴承挤压成形工艺进行数值模拟。基于正交试验设计,将轴承外圈挤压槽尺寸以及模具进给量作为工艺参数,选取轴承密合度、最大挤压力以及衬垫最大接触压力作为优化目标,采用综合平衡法进行优化设计,获得关节轴承挤压工艺参数的优化方案。试验结果表明,经过优化后,轴承内外圈间隙均匀,轴承密合度为0. 04 mm,符合产品质量标准,与原工艺相比,最大挤压力降低47. 3%,衬垫最大接触压力降低65. 6%。
For the problems of excessive extrusion force and uneven liner extrusion during the actual production of joint bearings,bearing YSG502 S12 was taken as the research object,and the extrusion process of bearing was simulated by finite element software LSDYNA.Based on the orthogonal experiment design,taking the extrusion groove sizes of bearing outer ring and the feeding amount of mold as the process parameters,and selecting the bearing tightness,the maximum extrusion force and the maximum contact pressure of liner as the optimization targets,the optimization design was conducted by the comprehensive balance analysis method,and the optimization scheme of process parameters for joint bearing was obtained. The experimental results show that after optimization the clearance between inner and outer rings is uniform,and the bearing tightness is 0. 04 mm,which meets the quality standard of product. Compared with the original process,the maximum extrusion force and the maximum contact pressure of liner decrease by 47. 3% and 65. 6%,respectively.
