摘要:

为拓展BC9型钢领钢丝圈的应用领域,通过研究钢丝圈气圈底端张力的特性,在平面钢领钢丝圈系统受力分析的基础上列出BC9型钢领钢丝圈平衡方程,并在考虑空气阻力和哥氏惯性力的情况下得出了气圈底端张力表达式,分析了其变化规律。根据高速摄影技术对气圈底角进行分析,得出气圈底角在-4°~5°之间变化。然后结合上述表达式给出不同卷绕半径下的气圈底端张力值,分析了气圈底角和卷绕半径对气圈底端张力的影响。结果表明,气圈底端张力随卷绕半径增加而减小,随气圈底角增加而增加,且卷绕大小直径时张力差异随气圈底角增加而增加。

Abstract:

In order to study about the yarn tension of the balloon bottom with BC9 ring, this paper presented the ring traveler balance equations based on the force analysis of the planar ring traveller system. Ant the tension expressions were obatined taking factors of the air-drag and the Coriolis force. Besides, the angles of balloon bottom variation from -4° to 5° were given by high-speed photography technology and post-processing. Then it gave the tension values combined with the tension expressions above. Furtermore, it analyzed the impact of the angles of the balloon bottom and winding radius on the yarn tension. The results indicated that the yarn tension of the balloon bottom decreased with the increase of the winding radius and increased with the increase of the angles of the balloon bottom. Moreover, the yarn tension difference between winding majou diameter and minor diameter, increased with the angles of balloon bottom increased.

Key words: BC9 ring traveller, air-drag, Corilois force, yarn tension of balloon bottom, high-speed photography technology
