The effects of source and load impedances connected to fluid transmission lines
Abstract
This paper presents the distributed parameter model for pneumatic fluid transmission line dynamics and relates the response of the line to geometric parameters and gas properties. Further, the less familiar cases of load resistance or capacitance and source resistance are presented and their effects upon the frequency response of the line are illustrated. It is shown that a load resistance causes signal attenuation even at low frequency; load capacitance causes reduction in bandwidth; and the output resistance of the driving source causes signal attenuation. Considerations in using the lines in fluid control systems are given.
