Abstract: The present application relates to the technical field of fiber winding control, and provides a tension control method of a multi-bundle winding equipment combined driving system, which solves the problem that the tension fluctuates greatly and cannot be output constantly in the fiber winding process. The method includes: establishing a tension control system fractional order mathematical model; establishing a time-varying fractional order PID controller; inputting a target tension value and an unknown external interference to the tension control system fractional order mathematical model, and outputting a real-time tension value; and calculating a difference between the target tension value and the real-time tension value and then inputting the difference into the time-varying fractional order PID controller, inputting an output value of the time-varying fractional order PID controller and the unknown external interference into the tension control system fractional order mathematical model, and outputting a real-time tension value until the real-time tension value output by the tension control system fractional order mathematical model approaches the target tension value. The tension value output by the control system according to the present application can be well stabilized near the target tension value; and the system has high robustness when the tension changes suddenly.

Abstract: This application describes a method for manufacturing storage containers by spirally winding with multiple bundles of fibers. Two sets of yarn guide nozzles distributed in a circumferential array form a first spiral winding structure and a second spiral winding structure respectively, and a spiral winding device with the two layers of spiral winding structures cooperates with feeding devices carrying wound containers, to realize the spiral winding of the multiple bundles of fibers on the wound containers; the feeding devices drive the wound containers to do axial reciprocating motion and axial rotation, and the spiral winding device drives the yarn guide nozzles to do radial telescopic motion and self-rotation motion; and according to the lengths of axial dimensions of the wound containers, single-station double-layer spiral winding or double-station single-layer spiral winding is selected.
