Study on the Dynamic Characteristics of the Winding Head

According to the structure and production processing requirements of polyester filament winding head, a finite element dynamic model of the winding system in parameters time-varying was established. By using the method of numerical calculation, the dynamic characteristics of the winding head were analyzed in three processes: rapid starting-up in empty volume, winding filament process and stopping in full volume. By studying the influence of the three processing under large stiffness coupling and soft stiffness coupling in the winding head, the role of the coupling stiffness and spindle structure was revealed in different working process.
