【摘要】:蓄能器作为液压系统中的重要辅件,对保证液压系统正常运行、改善其动态品质、保持工作稳定性、延长设备的工作寿命、辅助能源、降低噪声等起着重要的作用。所以,为液压系统选择合适的蓄能器也就显得尤为重要。 本文的核心是利用Visual Basic软件设计、编写蓄能器软件包。利用软件包可以方便、快捷和较为准确的计算蓄能器在7种不同工况下的工作参数并进行回路选择与仿真,即使在复杂的仿真过程中也无需打开AMESim仿真界面进行参数设置,只需在VBA编写的Excel界面输入参数进行仿真即可。 论文首先论述了蓄能器的性能、用途及类型;其次是总结推导了不同工况下蓄能器工作参数选择条件与计算公式,并且分析了温度、多变指数以及高压校正系数对蓄能器工作参数的影响,这些在软件包中都有所体现;再次,蓄能器在不同工况中发挥着不同的作用,为使蓄能器的作用更加显著,本文对蓄能器在两种典型工况下的作用进行了有无蓄能器的仿真对比研究;最后是蓄能器软件包的编程实现,蓄能器工作参数计算界面主要是利用Visual Basic进行编程,通过循环编程给出了较为精确的工作参数值,并且在后续的仿真结果中也验证了该计算的准确性,接下来根据计算数值可在蓄能器数据库中进行查询,添加蓄能器等动作,查询结果可以给出与计算结果匹配的蓄能器详细信息,然后用户选择要仿真的蓄能器回路在Excel仿真界面进行仿真,该界面通过AMESim中的AMEPilot与AMESim链接,在AMESim中设置用户在Excel仿真界面需要的输入参数与需要观察结果的输出参数,根据右下角的操作提示即可进行仿真分析。
[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.
