摘要/Abstract

摘要： 作为典型非轴对称回转体构件,复合材料方管在缠绕过程中要求满足稳定缠绕和均匀布满两个工艺条件。基于解析几何,分析方管缠绕丝嘴与芯模的空间关系,推导丝嘴运动轨迹方程,提出基于不滑线理论的方管小角度测地线缠绕设计方法;建立方管测地线周期缠绕理论,分析从不同起始点缠绕的实际误差;设计方管缠绕线型,并应用于实际缠绕,得到其小角度缠绕的一般绕线方程。结果表明,本文提出的方管小角度测地线缠绕理论正确,线型设计方法可靠,得到的丝嘴运动方程合理、精确,能很好地满足复合材料方管缠绕的基本原理和工艺要求。

Abstract: As a class of rotationally asymmetric bodies, design of filament-wound composite square tubes demands both windability and uniform coverage of winding patterns. Based on the analytic geometry, the spatial relations between the feed eye and the mandrel were outlined and the kinematic equations for coupling the motion of the mandrel and the feed eye were derived. Consequently, a design method for small-angle geodesic winding of composite square tubes was proposed, taking the non-slippage condition of winding trajectories into account. A periodically geodesic winding theory was presented and its winding error for various initial winding points was analyzed. The designed fiber patterns were then applied to the practical production of a composite square tube with small winding angles. The results show that the present design method for filament-wound square tubes is accurate and reliable. The obtained kinematic equations and motion laws of the feed eye and the mandrel satisfy the basic winding principle and manufacturability of filament-wound composite square tubes.
