The Effect Of Load And Cylinder Inclination To Displacement Speed Of Double Acting Pneumatic Cylinder

Abstract

Abstract : The effects of load and alignment of double acting pneumatic cylinder have been investigated. The cylinder used had the stroke length of 320 mm and the bore diameter of 20 mm. The electric circuit with double solenoid valve was selected to control the both extend and retract displacements of cylinder and to on/off of stop watch as well. The friction force was eliminated using bearing construction base.

The results show that the load has no effect to the speed of cylinder stroke in the horizontal, however the speed will decrease linearly with increasing of inclination in both of extend and retract strokes. The speed tends to decrease if the cylinder stroke has to raise the load and it will increase if the cylinder has to descend the load.

The simulation shows that the slower moving of cylinder resulted from either heavier load or higher inclination because the cylinder looks like to accumulate the pressured air before starting movement.
