“…For example, Zhang et al [35] used control valve, displacement transducer and pressure transducer to control the action of the measured pneumatic cylinder, and studied the characteristics of the maximum static friction, viscous friction and Coulomb friction of the pneumatic cylinder under different working pressures and temperatures. Wakasawa et al [36] utilized two proportional valves, a potentiometer and three acceleration transducers to study the dynamic behavior (friction and vibration characteristics) of the perpendicularly fixed pneumatic cylinder under test. Zhang et al [37] built a friction test rig based on speed regulating valve, directional valve, pressure transducer and displacement transducer, and carried out the friction characteristic test of pneumatic high-speed cushion cylinder.…”

In order to achieve high-precision pneumatic cylinder friction test, this paper proposes a new direct measurement method based on electric cylinder in which the axially acting forces from the compressed air in the two facing pneumatic cylinders cancel each other out and the detected value of the force transducer is just friction. For the sake of the implementation of the method, a new low-cost test method for identifying deadband of proportional directional valve was proposed, and a set of fuzzy PI constant pressure control system was designed to cope with a certain degree of leakage in the chamber. Based on the above, a friction test platform with two pneumatic cylinders facing each other was eventually built to study the influence of pressure, pressure difference, and piston speed on the friction of two commonly used different types of pneumatic cylinders. Through multiple sets of tests, it is found that when the lip seals are used in pairs between the piston and the inner wall of the cylinder, the friction between the piston and the cylinder is only related to the sum of the two chamber pressures, but not to the pressure difference between the two chambers; When the O-ring seal is used between the piston and the inner wall of the cylinder, the friction between the piston and the cylinder is related not only to the pressure of the two chambers, but also to the pressure difference between the two chambers. In addition, a series of comparative tests with the traditional single-cylinder friction test method directly demonstrate the effectiveness of the proposed new method.

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.
