Abstract
With the development of science and technology and industrial processes, hydraulic technology is increasingly used in the field of mechanical engineering. As an important auxiliary energy storage component in hydraulic systems, accumulators are also widely used. In modern society, the hydraulic system has higher and higher requirements on the performance of the accumulator. By studying the structural improvement and function of the accumulator, the economical, environmentally friendly and reliable hydraulic system can be further improved.
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. By combining the traditional accumulator with other hydraulic components, the volume and pressure of the gas in the accumulator are controlled, thus realizing the input stage. The function of adjustable energy storage capacity and controllable pressure in the output stage. This paper mainly carried out the following research work and got the following conclusions:
(1) Based on the working principle of traditional accumulators and related research results at home and abroad, the idea of changing the volume of accumulator gas is adopted to realize the controllable function of accumulator input and output.
(2) According to the research ideas and related fluid hydraulics knowledge, the complete circuit design of the energy storage integrated device with input and output control is completed, and the selection of relevant hydraulic components in the device is completed. According to the relevant operating conditions of the accumulator, the design and calculation of the performance parameters of the accumulator and the selection principle of the working pressure are briefly described.
(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.
