Pneumatic systems play a very important role in various sectors of industry and agriculture, including industrial automation systems. With the gradual evolution of automation systems, speed and accuracy, reliability, low friction, and long service life have become essential for pneumatic actuators. Having accurate information about the frictional characteristics of the seals used in pneumatic actuators leads to improved cylinder movement, optimization of the effective force of the jack (cylinder), and prevention of cylinder slippage. Consequently, achieving smooth and uniform cylinder motion is made possible, which results in higher mechanical accuracy of pneumatic servo systems. The internal friction force has a significant impact on the motion characteristics of the moving member in pneumatic cylinders. Determining the friction force in pneumatic cylinders is particularly difficult in cases where the moving member operates at high speeds and accelerations. This research aims to present a suitable method for determining the internal friction force in pneumatic cylinders. Therefore, the results of the experimental measurement of friction in this study indicate that friction in pneumatic cylinders does not depend solely on the type of seal material and the type of lubricant. Rather, piston movement speed, air pressure on both sides of the piston, and piston dwell time are among the effective and influential parameters on the friction force in pneumatic cylinders. |
