“…There are several previous analytical and experimental studies confirming that tension is the dominant factor that influences the stability in unwinding processes. [20][21][22][23][24] To analyze the unwinding behavior with respect to tension, the unwinding behavior in variable unwinding velocity according to the adhesive force of package was studied through the experiment. In addition, the adhesive was applied to part of crosssection and the behavior was analyzed to examine the problem that non-uniform adhesive property may cause.…”

In addition to the textile industry, unwinding of cable or fiber is used in various fields such as electronics, communication, and guided weapons. The cable released from the package exhibit a complicated behavior, entailing a combination of rotational and translational motion. This causes problems such as entangling and fracture. Therefore, it is necessary to study boundary and adhesion conditions to prevent unwinding failure. In this study, an experimental device for the analysis of cable unwinding was developed, and unwinding behavior was analyzed experimentally under various unwinding conditions. The experimental device comprises a jig for high-speed camera measurements, control device, and cable unwinding device. Cable behavior was analyzed according to the unwinding velocity and the distance between the fiber package and the point where the fiber was released. In addition, unwinding behavior with respect of the tension acting on the cable was analyzed experimentally by applying the adhesive.

“…After the 2000s, Lee et al, 18,19 Kim et al, [20][21][22] and Jang et al 23,24 expanded to research on cable unwinding in the transient state to overcome the previous limitations. Recently, Jang et al 24 derived the equation of motion for the unwinding system in transient state with time-varying unwinding velocity.…”

“…Cable unwinding under the steady state [3][4][5][6][7][8] has been examined, but these studies have difficulty analyzing the actual phenomenon of cable unwinding. In the 2000s, Lee et al, 9,10 Kim et al, [11][12][13][14][15] and Jang et al 16 expanded the study on cable unwinding from the steady state to the transient state. However, despite the efforts of previous researchers, studies had limitations in modeling cable unwinding systems with variable unwinding velocities.…”

In this study, the nonlinear unwinding behavior of cables in a transient state wound in a cylindrical spool package was analyzed using unwinding dynamics. In previous studies, investigations were conducted using constant unwinding velocity. However, this method is limited due to complexities regarding the analysis of the actual behavior where the unwinding velocity increases or decreases. In this paper, to prevent problems, such as twisting, entanglement, and cutting, that occur during the rapid unwinding process, an experimental device that converts unwinding velocity over time was developed. Using a cable unwinding system, high-speed camera, and tension sensor, the equation of motion, which was derived in a previous study using the expanded Hamilton theorem, was experimentally verified. Moreover, the cable’s tension change and behavior in the unwinding process were analyzed, and a method to solve the unwinding problem was studied.
