摘　　要：分析了QYJV-145D型气动V形牵伸摇架的结构特点,对粗纱定量、粗纱捻系数、细纱后区牵伸倍数、细纱后区隔距及相关工艺参数进行了优选试验。结果表明,气动V形牵伸机构在生产中适合大牵伸工艺,粗纱定量加重,成纱质量较弹簧摇架加压好。Structure speciality of QYJV-145D pneumatic V type draft cradle was analyzed. Optimizing test of roving quantum, roving twist factor, spinning back zone draft multiple, spinning back zone gauge and relative technology parameters were done, The result shows that pneumatic V type draft mechanism is suitable for large draft technology in production, and if weighing roving quantum, yarn quality is better than pressure of spring cradle.
