摘要
为了促进柱面摩擦限矩器在刮板输送机驱动系统上的应用,应用ANSYS有限元软件建立了数值模拟模型,仿真分析了给定油腔压力作用下柱面摩擦副的接触应力分布情况,通过公式得到了打滑转矩与油腔压力的关系,探讨了油腔长度、油腔厚度、油腔内径以及接触间隙对最大接触应力与打滑转矩的影响,并通过正交试验设计,得出了各因素对最大接触应力与打滑转矩的影响显著性排序。结果表明:通过数值模拟与正交试验设计相结合的方法,获得了柱面摩擦限矩器结构参数对最大接触应力与打滑转矩的影响,为柱面摩擦限矩器的结构设计及打滑转矩预测提供了理论依据。
In order to promote the application of cylindrical friction torque limiter in the drive system of scraper conveyor,the numerical simulation model was established using finite element software ANSYS,the contact pressure distribution of cylindrical friction pair under different oil cavity pressure was simulated and analyzed.The relationship between the sliding torque and oil cavity pressure was got by formula.Finally,the influences of oil chamber length,oil chamber thickness,oil chamber inner diameter and contact clearance on the maximum contact stress and slip torque were discussed.Through the orthogonal experiment design,the order of influence of each factor on the maximum contact stress and slip torque were obtained.The results show that through the combination of numerical simulation and orthogonal experimental design,the influence of structural parameters of cylindrical friction torque limiter on the maximum contact stress and slip torque are obtained.The results provide a theoretical basis for the structural design and slip torque prediction of the cylindrical friction torque limiter.
