并联状态流-压互补同步回路通过采用多个液流通径较小的分流阀,在有效降低各支路流量及分流阀阀芯液动力的基础上,提高阀芯的调节灵敏度和流-压互补回路的同步精度。通过数学建模,运用MATLAB软件中的Simulink模块,搭建了恒流状态下的分流阀同步回路、流-压互补同步回路和并联状态流-压互补同步回路,研究了3种仿真回路的偏载状态下的运行特性,验证了并联状态流-压互补同步回路的同步精度较分流阀同步回路和流-压互补同步回路有显著提高,为该回路在实际工程中的应用提供了理论依据。

The flow-pressure complementary synchronous circuit under parallel state can reduce the branch flow and hydraulic dynamic on the spool valve, and improve spool＇s adjustment sensitivity and the synchronization precision by several diverter valves with smaller flow path. The flow-pressure complementary synchronous circuit under paral- lel state, the diverter valve synchronization circuit and the flow-pressure complementary synchronous circuit are built based on the module Simulink of the software MATLAB. By analyzing these circuits＇ running characteristics under the partial load condition, we verify that the synchronization precision of the flow-pressure complementary synchronous circuit under parallel state is significant increased compared with the diverter valve synchronization circuit and the flow-pressure complementary synchronous circuit. This study provides a theoretical reference for practical engineering application of this circuit.
