摘要

本文对带软开关和不带软开关的数字液压系统的性能进行了数值比较研究。该系统基于现成的双向电磁阀。通过使用Modelica建模语言，采用了一种集总参数面向组件的建模方法。在OpenModelica环境下进行了数值模拟。所得的数值结果表明，软开关方法在高效节能的数字液压系统(如虚拟变量泵)中的潜在优势和局限性。

Comparative Numerical Study of Digital Hydraulic Systems With and Without Soft Switching

The paper submits a numerical comparative performance study of digital hydraulic systems with and without soft switching. The systems are based on off-the-shelf two-way solenoid valves. A lumped parameter component-oriented modeling approach is employed through the use of the Modelica modeling language. The numerical simulations are conducted in OpenModelica environment. The obtained numerical results demonstrate the potential benefits and limitations to soft switching methods in energy efficient digital hydraulic systems such as virtually variable displacement pumps.
