A DESIGN TECHNIQUE OF HYDRAULIC SERVO ACTUATOR SYSTEMS FOR EFFECTIVE POWER TRANSMISSION

Abstract

This paper presents a methodology on how the drive characteristic curve should effectively enclose the load locus on the non-dimensional force-velocity plane, when the sinusoidal movement of a hydraulic actuator against the external force is applied to the load with a mass, damper, and spring. Based on the geometrical configuration, it has been analytically shown that the optimum design specification of the hydraulic servovalve and cylinder can simply be determined by the non-dimensional parameters corresponding to the load condition.
