Influence and Utilisation of Pressure Propagation in Pipelines for Secondary Controlled Discrete Displacement Cylinders
Efficient discrete force control of cylinders may be realised by having multi-chambered cylinders,where the pressure of the chambers are shifted between fixed pressure levels of a secondary controlled system.However,the pressure shifting on a volume where the dynamics of pressure prop-agation is negligible have been be proven to have an unavoidable minimum loss due to the compress-ibility of the fluid.This paper investigates the effect of the pressure propagation in the connection and concludes that except more complex shifting schemes are introduced,the minimum loss remains un-changed.The paper analysis however also demonstrates and suggests,that with a clever valve control and shifting scheme,increased efficiency of a shift is obtainable by utilising the pipeline inductance.
