摘　　要：以非线性有限元法和多体动力学理论为理论基础,通过采用考虑剪切变形的二维梁单元的绝对节点坐标方程来描述钢丝绳的柔性变形,借助于单元节点相对于摩擦轮的线-线接触方法,建立了摩擦提升机摩擦传动系统的多点动态接触动力学模型。研究表明,构建的摩擦提升机多点接触动力学计算模型由于综合考虑了钢丝绳的柔性体效应、钢丝绳与摩擦轮之间的动态接触、摩擦轮转速、摩擦系数等因素的影响,为分析摩擦提升机提升过程中,摩擦接触处钢丝绳的接触力、张力、滑动、接触等摩擦传动特征提供了一个有效的研究工具。With the absolute nodal coordinates of rope, friction and dynamic contact, the flexible friction hoisting and contact dynamic model of transmission were established on the base of absolute nodal formula and contacting between lines. Dynamic model of friction hoisting transmission was applied to research on the contact vibration analysis and dynamic response of rope transmission such as transversal vibration and bend moment of rope, contact force, tension and so on. The results revealed that the new method and dynamic model could effectively calculate transverse vibration and contact vibration of friction hoisting transmission with multi - time varying factors and nonlinear factors. The simulation results provide basic data for dynamic design and valuable theoretical basis for further research on contact dynamics characteristics of friction hoisting transmission.
