摘要：为了精确计算环锭细纱机钢领板每次升降卷绕纱线的精确长度，以FA506型环锭细纱机传动结构为基础，分析对比在机械升降方式和电子升降方式下，近似算法和精确算法产生的绕纱长度差异，并探讨钢领板上升速度和前罗拉出纱速度与卷绕转角的关系。指出：近似纱长总大于精确纱长，且卷绕齿轮副Z_F/Z_G的近似值总比精确计算的小，不利于成形和高速络筒，故电子升降应采用精确算法；通过分析钢领板在上升状态时的瞬时速度和卷绕转角的关系式，可计算伺服电机的瞬时转速。

Abstract:In order to get accurate length of the winding yarn length at each lift of the ring plate of the ring spinning frame,based on the transmission structure of the ring spinning frame FA506,comparison analysis is done to the counting difference of the winding yarn length between the approximate algorithm and accurate algorithm both in forms of the mechanical lifting and the electronic lifting.Discussion is made to the relationship between the rising speed of the ring plate and the yarn throughput speed of the front roller and the winding angle.It is pointed out that the approximate yarn length is greater than the accurate yarn length,and the approximate value of the winding gear pair  Z_F/Z_G is smaller than that of the accurate calculation,which is not conducive to forming and high speed winding.Therefore,the electronic lifting should use accurate algorithm.Through analyzing the relationship between the instantaneous velocity and the winding angle at rising ring plate,the instantaneous speed of the servo motor can be worked out.
Key Words:ring spinning;winding forming;mechanical lifting;electronic lifting；yarn length;approximate calculating;accurate calculating
