Working Parameters Selection And Caculation Of Bladder-Type Accumulator Under The Different Conditions

As an important auxiliary part in hydraulic system, accumulator plays an important role to ensure normal operation, improve the dynamic quality of the hydraulic system, keep working stability, prolong the working life of equipment, assist energy and reduce noise etc. So, choosing an appropriate accumulator for the hydraulic system is particularly important.The core of this article is using of Visual Basic to design and program accumulator package. The characteristic of this software package is calculating accumulator working parameters under 7 different conditions and making accumulator loop simulation conveniently. Even in the complex process of simulation, it just needs to input parameters in excel interface programmed by VBA (Visual Basic Application) to simulate, does not have to open AMESim to set parameters.In this paper, first is to know the performance, uses and type of the accumulator; Second is summary and deduced accumulator working parameters selection and calculation formula of 7 different working conditions. It also analyzed the effects of the temperature, poly index and high-pressure correction factor to the accumulator working parameters. These are all embodied in the package. Third, accumulator plays a different role in different condition, to make accumulator functions more remarkable, we choose two typical working conditions to do the simulation, each loop did twice one have accumulator the other is without accumulator. The last is programming achieved of software package. Parameter calculation interface basically uses Visual Basic to program, it are given more precise value of accumulator working parameters by cyclic programming; according to the calculated value, it can query accumulator, add items and so on in accumulator access database; then given the matching accumulator detailed information; next, users select the accumulator loop to simulate in Excel interface. The interface links AMESim through the AMEPilot of AMESim. Setting input parameters and output parameters that the users need in the Excel interface in AMESim. There are some operating tips in the lower right corner; you can follow these tips to complete the simulation.
