Study on the Friction Characteristics of Cylinder Based on Stribeck Friction Model

Abstract

Abstract. In this paper, the friction characteristics of cylinder are studied based on the Stribeck friction model. By building the cylinder friction test rig, the experimental friction-velocity maps of the cylinder is obtained and the influence of the piston linear velocity on the friction force was studied. The friction force fitting model of the cylinder system was obtained by using the obtained data. It can be used to characterize the actual friction force, which can provide the definite reference value for the cylinder friction force in the process of the system work, and is an important step to friction compensation in the control system.
