ROTATIONAL AUTO-OSCILLATIONS OF RIBBED CYLINDERS IN A PNEUMATIC PRESSURE SUPPLY SYSTEM

Abstract

In modern textile production, improving yarn quality while increasing spinning machine speed remains challenging. The drafting system, particularly the fluted cylinders, largely determines yarn quality. Vibrations and self-excited oscillations of these cylinders increase product irregularity and reduce quality. The dynamics of delivery cylinder interactions involve time-dependent transitions, vibrations, and other complex behaviors, which are not well-studied due to their complexity and resource requirements. Yarn quality, process stability, productivity, and material efficiency also depend on the drafting components. Therefore, studying the rotational self-oscillations of fluted cylinders in pneumatic systems is crucial for enhancing spinning efficiency and maintaining stable yarn quality.
