摘要

摘要: 提出了一种新的滑线系数测量方法, 并基于一般曲面稳定缠绕条件, 设计了一种能够简便快捷测量滑线系数的新型芯模。该芯模在固定缠绕角情况下, 沿母线方向任意点处的纬度圆半径与该点的滑线系数之间满足线性关系。利用该方法及其装置对碳纤维和玻璃纤维在不同缠绕速度、缠绕张力和胶液黏度等条件下与铝质芯模间的滑线系数进行了测量表征。研究结果表明, 该方法可为缠绕纤维与芯模表面间滑线系数的测量及非测地线缠绕轨迹规划设计提供依据。

Abstract: Based on the stable winding condition of the general surface, a method for measuring the slippage coefficient was established. A special mandrel was proposed, which has a designed meridian profile that enables a linearly proportional relation between the cross-sectional radius and the measured values of the slippage coefficient. With the special mandrel, the slippage coefficient between carbon fiber/glass fiber and aluminum mandrel surface was obtained under several different typical filament-winding process parameters, such as winding speed, winding tension, resin viscosity, and so on. The experimental results show that this method can obtain the slippage coefficient easily and provide a reference for non-geodesic fiber path design.
