【摘要】：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。
[Abstract]:The parallel state flow pressure complementary synchronous loop can improve the sensitivity of the valve core and the synchronization accuracy of the flow pressure complementary loop by effectively reducing the flow capacity of each branch and the hydraulic power of the spool valve spool by using a plurality of shunt valves with smaller liquid flow diameters. Through mathematical modeling, using Simulink module of MATLAB software, build a constant flow diverter valve synchronization loop, under the condition of flow - pressure complementary synchronous circuit and parallel state flow - pressure complementary synchronous circuit, partial load operation characteristics under the condition of 3 kinds of circuit simulation, and verify the contact state flow - pressure complementary synchronous accuracy circuit is shunt valve synchronous circuit and the flow - pressure complementary synchronous circuit is improved, provides a theoretical basis for the application of the circuit in practical engineering.

【正文快照】： 引言在大流量液压系统中,多执行元件同步回路由于液流过程中液动力(瞬态液动力和稳态液动力)过大,使得分流阀阀芯两端弹簧刚度较大,阀芯调节不灵敏,分流误差较高;此外,由于系统还存在着偏载、泄漏、摩擦等问题,导致执行元件间的同步误差进一步加大。并联状态下的流-压互补同步
