不等开口纤维增强树脂复合材料缠绕壳体非测地线线型设计

线型设计是纤维增强树脂（FRP）复合材料缠绕壳体设计的一项重要研究内容，它对壳体FRP复合材料缠绕制品的质量起关键作用。本文针对不等开口极孔或不同形状封头的FRP复合材料压力容器壳体，基于非测地线缠绕方程，提出了一套非测地线缠绕线型设计方法，建立了根据已知缠绕线型和芯模转角来确定相应的切点数和纱片宽度的计算模型，开发出了一套FRP复合材料缠绕壳体仿真软件系统，对非测地线缠绕线型进行了计算机图像仿真与检验。结果表明:各个设计区间的仿真结果满足设计要求，没有出现缠绕角突变、纤维分布不规律和纤维在局部严重重叠等异常现象。该仿真软件系统可以为工程人员在实际壳体缠绕之前提供参考，缩短缠绕线型迭代试错周期，同时也为后续缠绕角及缠绕顺序等缠绕参数的优化奠定了基础。 

Winding pattern design of fiber reinforced resin polymer composites winding vessels with unequal polar openings based on non-geodesics

Filament winding pattern design is an important research field in the design of fiber reinforced resin polymer (FRP) composites winding shell and it plays an important role for filament winding products. A complete non-geodesic design method was proposed for unequal polar openings shell or different dome shapes shell based on non-geodesic equations. A model was established to obtain the number of tangent points and roving width by mandrel rotation angle and winding pattern. A FRP composites winding simulation software system was developed based on the winding pattern design method, the simulations of computer graphics and tests for non-geodesic filament winding were realized. The simulation results in every section meets design requirement which do not indicate abnormal phenomena such as winding angle saltation, irregular fiber distribution and heavily fiber overlap. This filament winding software system can help project planner decrease winding pattern trial and error times and lay the foundation for the optimization of winding angle and winding angle sequence.
