Hydro-pneumatic accumulators are used to improve the features of different kinds of hydraulic systems and they are common in industry and mobile applications. In order to include functionality of accumulators to hydraulic system models, an accurate yet light simulation model of hydro-pneumatic accumulator is needed. In this paper a simulation model of a piston type hydro-pneumatic accumulator is presented. The simulation model takes into account of the behavior of friction, nitrogen gas and hydraulic ?uid. The simulation model was validated by comparing the simulation results to measurement results obtained from laboratory tests, and strong correlation was found between them. The model is suitable for researchers as well as for engineers in designing work in industry.
