Study on viscoelastic friction and wear between friction linings and wire rope

摘要

The purpose of this paper is to establish the relationship between dynamic viscoelastic friction and wear. Friction and wear mechanisms were analysed by dynamically monitoring the viscoelastic slippage and temperature of the friction interface. The results show that the friction coefficient was positively correlated with the loss factor. Friction and wear both decreased with the increase of the interfacial friction temperature. The wear increased exponentially with the increase of the loss factor. Friction and wear properties of three types of friction linings were compared; the loss factor of K25 lining was the largest (0.21); the sticking time of the K25 lining was the longest (0.27 s), and its friction coefficient was the largest (0.67) in the early stage of the friction experiment. As the friction experiment progressed, the temperature of the interface increased. The loss factor and the friction coefficient decreased noticeably with the increase of temperature. This resulted in less friction, less surface damage and fewer cracks and debris. The wear of the K25 lining was the smallest (0.32 g).
