The friction failure between the fluff of the sealing strip and the window glass is a typical type of friction characteristics.In this paper,the friction characteristics of the friction pair interface composed of sealing strip fluff and glass are analyzed from water to dry friction by repeating the simulation test in the laboratory,and the change of friction characteristics is observed by loading and unloading when the test has obvious vibration,and the test process is divided into five different stages from wet-semi-dry-wet-dry to dry,and the friction characteristics and the mechanism of the test are discussed.The results show that the friction coefficient of the friction pair is the smallest in the semi-dry,dry and wet state,and the obvious vibration occurs in the test,and the vibration is obviously aggravated when the load is increased at this time,and the friction coefficient returns to the level before loading after unloading.During the whole test,the friction state of wet and dry state was more stable than that of semi-dry and wet state.
