Friction free yarn twisting on the basis of superconducting technology and in consideration of the dynamic yarn path in textile machines

本课题旨在研究一种基于超导磁轴承（SMB）的新型纺织机械绞环元件系统，通过理论建模、仿真和计量研究，对这种新型纺织与超导技术的结合进行动态纱线路径下的研究。在项目的第一个阶段，已经开发了在环锭纺纱机中引入SMB加捻元件系统的理论和实验基础，该系统可以实现高达25,000 rpm的无故障纺纱过程。分析了工艺、技术和超导参数之间的相互作用，推导了SMB扭转元件系统的规律。第二个资助阶段将探索SMB捻线元件在纱线动力学，非线性纤维膨胀行为以及SML和纱线在更高主轴转速高达50,000 rpm时的振动行为。随着该项目的完成，作为中心目标，超导磁轴承在高速纺织和加工机械中的应用具有了科学依据。

The aim of this research project is the study of a novel ring-twisting element system on the basis of a superconducting magnetic bearing (SMB) for textile machines, through theoretical modeling, simulation and metrological investigation of this novel combination of textile and superconductor technology under dynamic yarn path.In the first project phase, the theoretical and experimental basis for the introduction of a SMB twisting element system in the ring spinning machine have been developed, which allow a trouble-free spinning process up to 25,000 rpm. The interactions of process, technology and superconducting parameters were evaluated and laws for the SMB twisting element system were derived. The second funding phase will explore the SMB twisting element with regard to the yarn dynamics, nonlinear fiber expansion behavior and the vibration behavior of the SML and the yarn at higher spindle speeds up to 50,000 rpm. With the completion of this project, as a central objective, the scientific basis for the use of superconducting magnetic bearings in high-speed textile and processing machines is available.
