摘　　要：从理论上分析比较了圆弧、抛物线作为玻璃纤维络筒机槽筒沟槽转向曲线时槽筒的运动特性和动力特性,在此基础上提出了新的运动规律,推导了运动方程。作为一项理论研究参考,可以为玻璃纤维络筒机提供更为理想的导纱规律设计方法。采用五次多项式运动规律来设计转向曲线,以消除凸轮两端折回处的柔性冲击,改善槽筒导纱机构的冲击。From theoretical analysis, the kinematic and dynamic characteristics of the grooved drum of glass roving winders are compared between using arc and parabola as the return curve on the grooved drum, based on which a new equation is deduced from a new kinematic law. It can be used as a theoretical reference in the design for more ideal law of traverse motion. A five-ordered polynomial curve is designed as the return curve to avoid soft shock at the return phase of the cam and improve the shock behavior of the guide mechanism.
