| contents | Relevance of an Energy Dissipation as a Condition of a Stable Reeling Off of a Yarn from a Yarn Accumulator Liudmila Oleynikova José Antonio Gómez-Reyna Alla Kabatskaia Ivanovna Ingeniería Yarn jerk balloon tension friction The problems of a yarn movement and yarn tension stabilization when a yarn is reeled off from cylindrical feeders and balloons are considered. The applications of the main laws of mechanics to a part of a moving yarn with the aim to evaluate its tension lead to different results if to assume a case of reeling off without energy dissipation. The application of momentum conservation law leads to result for yarn tension value which is more than twice bigger than correspondent result following from the application of energy conservation law. Taking into account possible energy dissipation during a yarn movement resolves this contradiction. It also shows that there is necessary level of energy dissipation to insure a stable yarn movement. It explains why in a number of situations a yarn often moves by jerks and vibrates although a speed of its end, by which it is drawn, and other conditions of reeling off are maintained constant. Stabilizing influences of air resistance and additional friction are considered and evaluated. 2011 artículo científico 1665-0654 https://www.redalyc.org/articulo.oa?id=61419301006 en http://www.redalyc.org/revista.oa?id=614 Científica application/pdf Instituto Politécnico Nacional Científica (México) Num.1 Vol.15 |
