Abstract
In pneumatic system design, it is very important to understand characteristics of every related factor in advance. Pneumatic pipes have a significant effect on the behavior of pneumatic system dynamic characteristics. Therefore, it is necessary to analyze the characteristics of the pipe connected to a chamber for the purpose of designing pneumatic systems. The measurement of valve flow rate characteristics has been defined by JIS. The purpose of this research is to investigate the method based on JIS in measuring valve orifice. The proposed model gives some special importance to pneumatic chamber system including the influence of the pipe between the solenoid valve and chamber, and the pipe effect on orifice coefficient Kt also was cleared. Experiments and simulation onsidering the pipe influence are conducted and they are in good agreement.
