钢丝绳

This thesis DESign steel wire tension control system of Steel Billet Grinding Machine, and establish mathematical model of every component in electro-hydraulic proportional valve control dissymmetry hydraulic cylinder servosystem and the load with large inertia and flexibility system of Grinding Machine. Through the medium of matlab/simulink simulation, this thesis mostly analyses Pre-load impact of steel wire stress. Compare with the emulation result of non-feedback, force feedback, displacement feedback, thereby educe reliable conclusion.
