根据电梯曳引轮上钢丝绳的受力情况,建立钢丝绳在曳引轮上发生滑移后的数学模型。经过计算分析,得到电梯曳引钢丝绳在空载与满载时滑移量之间的关系,以及空载与125%额定载荷紧急制动时钢丝绳滑移量之间的关系,同时利用Matlab GUI设计了人机交互界面。这对监测电梯的曳引情况和处理现场问题具有参考价值。According to the force of the traction system stressed on the rope of the traction wheel,the mathematical model of the traction rope slip is built.Through computational analysis,the relationship between the no-load and full-load slippage amount of the elevator traction rope is proposed,and the relationship between the no-load and 125%rated-load is proposed.The man-machine interface is designed by Matlab GUI.Reference value to monitor elevator system traction conditions and to solve field failure is given.
