摘要
为解决复合弯管生产过程中产品质量不稳定和生产成本较高等问题,提出了一种采用2轴计算机控制缠绕机来实现复合弯管缠绕成型的方法.该方法采用测地线和非测地线对弯管和直管部分进行了纤维缠绕路径设计,给出了不滑线、不架空缠绕的边界条件,并结合面片缠绕理论对复合弯管进行缠绕节点设计,给出了弯管外侧线型布满条件来分析弯管内侧纤维重叠情况,并编制缠绕控制程序来验证该缠绕方法的实用性.运行结果表明:该成型方法具有硬件结构简单、成本低且缠绕线型稳定、高效等特点,能够满足各种复合弯管的缠绕需求.
To improve the product quality of combined elbows and reduce the production cost,2-axis computer control filament winding machine was designed to wind the combined elbows.Geodesic and non-geodesic theory was used to design the fiber winding trajectory of elbow and tube.The boundary condition without slippage and bridging and the overlay condition of the maximum arc on the elbow were given.The winding nodes were designed with the patch winding theory and the overlap condition of the minimum arc on the elbow was analyzed.The winding control program was written to verify the practicability of this winding method.The result shows that the winding process has the advantages of simple structure,low cost,high productivity and stable pattern.It can meet the winding requirements of all combined elbows.
