Co-simulation research of automatic jumping control system of hot strip mill coiler

The dynamic model was established with the tool of ADAMS software for Coiler on the 1700 product line of a steel factory and AJC (Automatic Jumping Control) system model of wrapper equipment was built by AMESim software. Then the dynamic co-simulation of hydraulic, control and mechanical system was achieved. Based on the multiphase-match model, the jumping trace of the aid-roll, changing rules on loading and pressure of hydraulic cylinder were worked out; effects on different parameters of AJC system were also discussed. Conclusions show that the hydraulic servo control system can achieve the required accuracy and speediness; a valid theoretic basis for design and technique alteration of coiler is provided also.
