DYNAMIC CHARACTERISTICS ANALYSIS OF A YARN DRAWING MACHINE FRAME USING THE FINITE ELEMENT METHOD

Abstract

This paper presents the process of constructing a three-dimensional geometric model of a welded frame for a spinning machine, composed of box girders and structural steel, to accurately reflect the actual structural characteristics of the machine. Based on the established geometric model, deformation, displacement, and natural vibration analysis of the frame were performed using the finite element method in the ANSYS software environment.

Through the numerical model, the characteristic natural vibration modes, corresponding vibration frequencies, and the distribution of deformation and displacement of the frame were determined and analyzed. The results obtained allow for a quantitative assessment of the dynamic characteristics of the frame structure, while also identifying regions with a tendency to concentrate deformation and sensitivity to vibration during operation. Based on this, the research provides a scientific basis for considering and proposing solutions to enhance the rigidity and improve the dynamic stability of the spinning machine frame, contributing to increased reliability and operational efficiency of the equipment.
