【Abstract】 A new concept of static-hydraulic system with secondary regulation was proposed,extending the coupling concept from the pressure coupled system to the flow coupled system.The basic configuration,the working principle and the characteristics of the flow coupled system with secondary regulation(FCSSR) were introduced and the differences between FCSSR and the traditional pressure coupled system with secondary regulation and between FCSSR and the traditional flow coupled system were analyzed.A mathematical model was established for FCSSR,and the test was performed.Test results indicate that FCSSR can recover and reuse the potential energy of the weight and realize the power matching among the electric motor,the hydraulic accumullator and the load.更多还原
