Abstract:The time-variant & nonlinear dynamic model for the mechanical-electrical system of the skip winding equipment being accelerated was put forward firstly, in which an AC motor was controlled through multi-pieces of resistances in series. On the basis of the model and by using computer simulation technique, the kinematic & dynamic laws of the winding vehicles and the winding engine with 8-pieces and 6-pieces of resistances in series were gotten respectively. The proposed model and ways as well as the discovered phenomena and laws are fresh and can be the theoretical basis of improving the old type of winding system, especially the one improved with computer control technique, and it is helpful greatly to design other forms of winding system driven by AC motors or DC motors.
