| Abstract: | This paper introduces the basic composition and working principle of the perpendicular force loading system of a servo proportional test-bed in Shenyang University of Technology,which is based on hydraulic servo proportional control technology,intelligent data acquisition and control technology.The closed loop control system takes the proportional directional valve as control element,takes force sensor as feedback element,to realize the precise control to force output of asymmetric hydraulic cylinder.The dynamic response mathematical expression of the system is derived,the dynamic simulation of the system is carried out by MATLAB/Simulink,and the simulation results are obtained. |
