Modeling and Simulation of the Operation of the Hydro-Pneumatic Accumulators

Abstract

This paper introduces some mathematical models and simulations of the operation of the hydro-pneumatic accumulators from the hydraulic actuation systems. There are presented static but also dynamic models that can be used in the design of the hydraulic units. The operation in dynamic mode was simulated by means of specialized programs such as Matlab/Simulink and Automation Studio. A real, numerical example, which was the basis for the achievement of a hydraulic unit intended for machine-tools, was also presented.
