A dynamic modeling approach to the moving filament during high-speed winding by absolute nodal coordinate formulation

Abstract

During the winding process, the filament moves at a high speed with multiple configurations and large deformations, and is acted upon by winding tension, contact force, transverse force, air resistance, and so on. Accurately predicting the trajectory and tension fluctuation of the filament under the high-speed running condition is the basis for regulating winding parameters and ensuring high-quality winding. This paper proposed a novel dynamic approach for modeling the polyester filament winding system. The filament element was established by absolute nodal coordinate formulation. The nonlinear spring and viscous damper elements were used to establish the contact model between the filament and the mechanical parts, and the mechanical model of the influence of the airflow on the filament was established. Through considering the moving filament and all the force factors, the dynamic model of the multi-body coupling system of the filament winding and the corresponding nonlinear dynamic equation were established, and the dynamic equations were solved using MATLAB. An example of the high-speed winding system was simulated and further analyzed, and the simulated trajectory of the moving filament was highly consistent with the experimental image record.

Dynamic behavior analysis of the winding system during filament reversing pushed by the traverse mechanism

“…However, the curves of Node 3 present a different variation, which is mainly caused by the draft of the filament during winding and the winding stability point being undefined in the modeling process. In addition, comparing the motion trajectory of the filament with the curves from Li et al., 23 the results demonstrate that the methods proposed in this thesis are correct and efficient.…”

“…Lu et al 22 proposed the linear magnetic reciprocating yarnguiding system and investigated the motion characteristics of the reciprocating yarn-guiding mechanism. In addition, Li et al 23 investigated the dynamic characteristics of the winding system during traverse conditions, considering the viscoelasticity of the filament. These works in the literature have attempted to analyze or explain the winding process and the impact of the traverse yarn-guiding system using different research types, but have not studied the dynamic behavior of the moving filament during reversing.…”
