摘要: 针对回转体构件纤维缠绕过程中纱线由出纱机构缠绕到主轴上存在的摩擦阻力及悬纱长度的变化引起落纱点处纤维张力变化的问题,提出基于张力补偿的变张力控制方法。分析纱线以任意包角经过导辊前后的张力关系,并采取测地线的缠绕理论对出纱导丝头运动轨迹进行规划,获得出纱导丝头的运动轨迹方程;建立芯模缠绕数学模型,分析芯模缠绕过程中悬纱长度对张力变化的影响,获得在不同落纱点处的张力与出纱端需要提供的张力的关系,对悬纱长度变化引起的张力波动施加补偿,从而使落纱点处张力值恒定。进行了施加张力补偿的回转体纤维缠绕实验,缠绕实验结果表明,施加张力补偿后,缠绕张力更加稳定,验证了提出的基于张力补偿的变张力控制方法能有效抑制缠绕过程中张力的波动。

Abstract: Aiming at the problem of the friction resistance and the change in suspension length caused by the fiber tension change at the doffing point when the yarn is wound from the yarn outlet mechanism to the main shaft in the process of fiber winding of rotary components, a variable tension control method based on tension compensation is proposed. The tension relationship of yarn before and after passing through the guide roller at any wrap angle is analyzed. The trajectory of the yarn outlet guide head is planned by the geodesic winding theory, and the trajectory equation of the yarn outlet guide head is obtained. The mathematical model of mandrel winding is established, and the influence of suspension length on tension change during mandrel winding is analyzed. The relationship between tension at different doffing points and tension needed to be provided by the doffing end is obtained, and the tension fluctuation caused by suspension length change is compensated, so that the tension value at doffing point is constant. The fiber winding test of rotary components with tension compensation is carried out. The winding experiment results show that after adding tension compensation, the winding tension is more stable. It is verified that the proposed variable tension control method based on tension compensation can effectively suppress the fluctuation of tension in the winding process.
