摘要
以JKM4.5×6型提升机摩擦衬垫为研究对象,运用数值模拟技术,对摩擦衬垫进行实际工况下的有限元分析,考虑绳槽深度与绳槽围包角对摩擦衬垫接触应力与变形影响,优化摩擦衬垫结构尺寸。研究结果表明:通过比较同一深槽直径下,不同绳槽深度和围包角模型的有限元计算结果,确定了在使用直径为44mm钢丝绳的工况下,绳槽尺寸最优解为绳槽直径为46.6mm、绳槽深度为22mm、绳槽围包角为130°;由标准绳槽模型和新型绳槽模型的应力变化曲线发现,应力波动范围从2.7~4.1MPa减小至1.24~1.86MPa,波动值相差约54.7%,应力减小约30.14%。最大变形量从0.15mm减小至0.11mm,相差约32.37%。
With JKM4.5×6 hoist friction liner as the research object,using numerical simulation technology,the finite element analysis of the friction pad,considering the rope depth of the groove and the envelope Angle of the friction pad contact stress and deformation,optimize the structural size of the friction pad.The research results show that:by comparing the finite element calculation results of different rope groove depth and envelope angle models under the same deep groove diameter,the optimal solution of 44mm is that the diameter of 46.6mm,the depth of 22mm and the envelope Angle of rope groove is 130;From the stress change curve of the standard rope trough model and the new rope trough model,the stress fluctuation range decreases from 2.7~4.1MPa to 1.24~1.86MPa,the fluctuation value varies by about 54.7%,and the stress decreases by about 30.14%.The maximum deformation amount decreased from 0.15mm to 0.11mm and varied by about 32.37%.
