Özet

In this study, the effect of pressure increase rate and threshold speed parameters on the maximum static friction forces in pneumatic cylinders’ onset of motion was investigated. In order to investigate the effect of these two parameters, a series of experiments at different pressure increase rate and threshold speed values were carried out on a pneumatic cylinder in real time with MATLAB/Simulink. In these experiments, an incremental pressure starting from zero was applied to the relevant pressure chamber of the pneumatic cylinder by means of a pressure regulating valve, and the instant of the first movement was accepted as the point where the determined threshold speed was first exceeded. These two determinative parameters with different values were selected and tested. The results of the experiments shown that the pneumatic cylinder has different friction force values. When the data obtained were examined, it was seen that the pressure increase rate applied to the pressure chambers had a considerable effect on the static friction force value and the threshold speed parameter slightly affected the static friction force results. As a result of this study, it is clearly understood that in calculating the static friction force of pneumatic cylinders, the pressure increase rate and the threshold speed values should also be taken into account.
