Water-lubricated rubber stern bearings are prone to stick-slip phenomena under low speed and heavy load conditions. To explore this mechanism, a series of experiments were carried out on a visualized glass axis based on machine vision technology. The results suggest 1) at the frictional vibration is load-dependent at low speeds, 2) that frictional force can be accurately determined by the proposed method, and 3) that the proposed setup yields informative visualizations of frictional vibration

Frictional vibration is a common but not entirely understood tribological phenomenon in water-lubricated rubber stern bearings. This paper proposes a transparent glass cylinder and rubber block model which reveals the frictional contact area under a high-speed camera. The local displacements of different grid points on the contact area can be measured by machine vision. A conjoint analysis method for friction coefficient, vibration, noise, and image information is used to determine the mechanisms of frictional vibration. The frequency of noise accompanying the vibrations can be exploited to di...
