摘要

摘要在轧棉过程的初始位置,由于纤维的张力,种子被拉到刀筒接触间隙的缝隙中。随后,种子受到某种冲击。在搅拌器的冲击之后,纤维与种子的分离是顺序发生的,而不是同时发生的。理论和实验研究的结果表明,种子上冲击脉冲的最佳频率(f=18-20)在提供种子和纤维的最佳质量指标方面是技术上最成功的。共振模式下的敲击允许降低种子上的冲击脉冲的大小,从而降低对种子的损伤程度。此时,位于股线末端的种子仅在弹性恢复力的作用下移动。在动态过程中纤维束部分的活性部分可以小到0.001或更小。实验测定了原棉品种BA-440的柔顺系数的平均值。这允许间接地确定挥发物的刚度系数。根据所获得的参数,系统的动态状态实际上落入参数共振区域,其中运动是不稳定的。这意味着,在搅拌器的冲击后,线束末端受损的种子显著增大,导致种子与纤维分离。

Investigation of the Process of Separation of Fibers From Seeds During Roll Ginning
Abstract In the initial position in the process of roll ginning, the seed is drawn to the slot of the contact gap of the knife-drum due to the tension of the fibers. Subsequently, the seed is struck with a certain impulse. The separation of the fibers from the seed after the impact of the beater occurs sequentially, not simultaneously. As a result of theoretical and experimental studies, the optimum frequency of the shock pulse on the seed (f = 18-20) was found to be the most technologically successful in terms of providing the best quality indicators of seeds and fibers. Beating in the resonance mode allows to reduce the magnitude of the shock impulse on the seed, leading to a reduction in the degree of damage to the seeds. At this moment, the seeds at the end of the strand move only under the action of an elastic restoring force. The active part of the fiber bundle section in a dynamic process can be as little as 0.001 or less. The average value of the compliance coefficient for the raw cotton variety BA-440 was determined experimentally. This allowed to determine the stiffness coefficient of the volatiles indirectly. According to the parameters obtained, the dynamic state of the system practically falls into the region of parametric resonance, where the motion is unstable. This means that the damaged seeds at the end of the strand enlarge significantly after the impact of the beater, causing the seeds to separate from the fibers.
