摘要

The influence of hydraulic and mechanical coupling on control property is analyzed in the secondary regulation servo loading system for the transmission bridge of heavy vehicle. Simulation shows that disturbance error caused by mechanical coupling between the speed control subsystem to simulate the drive and the torque control subsystem to simulate the loads on the secondary axle and wheel edges is comparatively large and may obviously decrease the control accuracy of the whole system. Certain decoupling control elements can be installed to the system so as to make each subsystem almost independent of each other, realize decoupling of the secondary regulation servo loading system, eliminate deteriorating effect of coupling and finally quite improve control property. The decoupling strategy proposed provides an efficient way to realize decoupling control of the servo loading test equipment and to enhance its performance.
