In this paper, the related research is carried out on the problem of realizing the controllable function of the input and output of the accumulator.

(3) For the performance study of accumulator, the mathematical model of accumulator is established, and the relevant parameter factors affecting its performance are obtained. The basic equations are obtained for the force analysis of the piston rod set of the booster cylinder. The basic equations are established for the energy density of the energy, and the parameter factors affecting the working efficiency are obtained.
(4) For the working process of the accumulator, the whole energy storage device was modeled, dimensioned and simulated on the AMESim software platform. Through the simulation, the pressure of the accumulator, the quality of the hydraulic oil in the accumulator and the displacement curve of the piston group during the process of liquid inlet and discharge were obtained. The working process of the accumulator was further studied.
(5) Based on the influence of relevant parameters on the performance of the accumulator, based on the AMESim simulation platform, a series of accumulator pressures are obtained by comparing the accumulator pre-inflation pressure, the preset constant pressure value and the piston area ratio. The variation curve of the relevant parameters further obtains the result of the influence of the parameters on the performance of the accumulator.
