Abstract
In this study, transient response of a pneumatic transmission line terminated by volume is analyzed by high speed and accurate computing technique applying the characteristics method.
The dimensionless parameters RN, RV and RH are derived by introducing the dimensionless variables for the basic equations of the system. Then, the transient response of the system can be determined by these dimensionless parameters. The parameter RN represents the viscous friction of the line and determines the damping coefficient of the line, and RV is the ratio of the volume of a chamber to that of the line. The parameter RH represents the extent of the heat transfer in the chamber.
The results of the numerical computation agree well with the experimental results. The typical step responses are shown by figures and are available to the design of the pneumatic systems.
