Dynamic properties of traversing rod

Abstract

The paper deals with an analysis of traversing rod dynamic properties. The traversing rod is a part of winding mechanisms on rotor spinning machines, and transmits periodical linear traversing motion from motor to yarn guides. The rod is specific by its very thin and long shape where the ratio between length and diameter reaches almost 4,000:1. Due to a demanding exciting motion it is subject of high dynamic load resulting in mainly longitudinal vibrations. In order to better understand the behaviour of the system, several measurements of material and dynamic properties of the rod were carried out. Moreover a mathematical model of the rod was created and loaded by the requested motion. The performed analysis disclosed new information about the dynamic behaviour of the rod. However, the results confirmed the assumptions that the rod poses limiting factor in reaching high speeds.
