Influence of external environment parameters on friction coefficient between hoisting-rope and its pads
Source abstract
Abstract
The friction coefficients between the hoisting-rope and friction pads made of different materials under different environmental conditions, load sizes, and load frequencies were investigated by using a friction and wear tester. The variation law of the friction coefficient with the change in the working condition parameters was explored through orthogonal test analysis; it is found that dry friction, a load of 100 N, and a frequency of 1 Hz are the optimal working conditions to achieve an optimal friction coefficient of the matching pair of the hoisting-rope and friction pads. Among them, the friction coefficient of the K25 pad is greatly affected by the environment, while the friction coefficient of the G30 pad is greatly affected by load. The results under all working conditions show that the friction coefficient of the K25 pad is greater than that of the G30 pad but the wear resistance of the G30 pad is better than that of the K25 pad. In terms of wear resistance, the K25 pad performs better under dry friction conditions than under other environmental conditions, while the G30 pad performs better under rain conditions. The conclusion can provide theoretical guidance for the reasonable matching between the hoisting-rope and its pads under different environmental conditions.
