双胶圈牵伸系统的压力分布函数

Pressure Distribution Function of Drafting System with Double Apron

文章运用弹性力学和接触力学的分析方法,着重对环锭细纱机牵伸系统双胶圈部分的压力分布进行了研究,建立了整个牵伸系统的压力分布函数,与实测分布函数曲线对比发现两者具有较高的一致性。该函数的构建将对牵伸理论的研究、牵伸工艺的优化及牵伸装置的改进具有一定的指导意义。

In this paper, the methods of elastic mechanics and contact mechanics were used to ana- lyze and research pressure distribution of the double apron of drafting system on the ring spinning frame, and the pressure distribution function of the whole drafting system was built. By comparing the curve of measured distribution function, they had a high consistence. The function provided refer- ences for the researches of drawing theory, the optimizations of drafting process and the improvements of drafting devices.
