Abstract
In recent years, with the need to reduce the time required to complete the cycle of automatic assembly machines, the high speed driving of pneumatic cylinders has become an important subject of research. Under certain driving conditions, it has been found that the velocity response as well as the pressure response of the air in the cylinder chamber displays an oscillatory behavior. In this report, a detailed examination using a numerical analysis is conducted in order to grasp the nature of this phenomenon. From this result, it was found that this oscillatory phenomenon becomes increasingly evident in the velocity response as well as the pressure response when the pneumatic cylinder is driven at a high speed. Thus, an analysis is first conducted to investigate the cause of this oscillatory phenomenon. Thereafter, an ideal driving method for obtaining high speed is proposed where this oscillatory response of the velocity is used positively.
