[Abstract]:Accumulator, as an important auxiliary part of hydraulic system, plays an important role in ensuring the normal operation of hydraulic system, improving its dynamic quality, maintaining working stability, prolonging the working life of equipment, auxiliary energy and reducing noise.
The core of this paper is to use Visual Basic software to design and compile accumulator software package.It is convenient, fast and accurate to calculate accumulator working parameters under seven different working conditions and select and simulate the circuit.Even in the complex simulation process, it is not necessary to open the AMESim simulation interface for parameter setting. You need to simulate the input parameters of the Excel interface written in VBA.
Firstly, the paper discusses the performance, use and type of accumulator; secondly, it summarizes and deduces the selection conditions and calculation formula of working parameters of accumulator under different working conditions, and analyzes the influence of temperature, changeable index and high pressure correction coefficient on the working parameters of accumulator, which are reflected in the software package; thirdly, the accumulator is different in different conditions. In order to make the accumulator play a more significant role, this paper makes a comparative study on the simulation of accumulator under two typical working conditions. Finally, the accumulator software package is programmed and realized. The interface of accumulator working parameters calculation is mainly programmed by Visual Basic, which is programmed by cyclic programming. Cheng gives a more accurate value of working parameters, and in the subsequent simulation results also verify the accuracy of the calculation. Next, according to the calculation value can be queried in the accumulator database, add accumulator and other actions, the query results can give the accumulator details matching the calculation results, and then users choose to simulate. The accumulator circuit of AMESim is simulated in Excel simulation interface. The interface links AMEPilot and AMESim in AMESim, and sets the input parameters and output parameters needed by users in Excel simulation interface. The simulation analysis can be carried out according to the operation hints in the lower right corner.
