Abstract:The mathematical model was presented for the servo loading system with secondary regulation. Control performance under the disturbance of hydraulic and mechanical coupling was simulated with MATLAB. Simulation reveals that increasing of load pressure, output torque and rotational speed may deteriorate control precision. Load pressure fluctuation causes more influence on torque control system than on speed control system, while torque fluctuation causes more influence on speed control system than speed fluctuation does on torque control system.
Key words: secondary regulation; hydraulic coupling; mechanical coupling.
1. Introduction
The servo loading system with secondary regulation is a newly developed loading technology which applies to simulation loading experiment of engines, gear-boxes, transmission-bridge of vehicle and many rotary elements in recent years. It is a advanced system with high efficiency and proper dynamic performance which can also realize energy recycling as well as flexible and rel
