- 纤维缠绕复合材料容器在航天领域得到广泛应用,为满足复材容器快速方案设计需求,对比分析了缠绕线型和封头子午线类型对复材容器性能的影响,通过建立简化的复材容器几何参数模型,基于成熟可靠的网格理论和测地线理论,详细推导了螺旋缠绕封头、螺旋缠绕椭球封头、平面缠绕封头和平面缠绕椭球封头等4种封头的控制方程。对应每种封头,均进行实例计算以验证设计方法的正确性,结果表明:相同纤维缠绕线型的子午线、缠绕角、壁厚、纤维应力以及综合性能参数等设计结果相似,推荐采用螺旋缠绕椭球封头或平面缠绕椭球封头以避免子午线曲率拐点,同时有利于加工制造。
- Abstract:
- Filament-wound Composite Pressure Vessels(FCPV)has been widely used in the aerospace field.The main purpose of this paper is to meet the requirements of rapid concept design of FCPV and compare the effects of winding pattern and meridian type of domes on the properties of FCPV.A simplified geometric parameter model of FCPV was established.Based on the mature and reliable grid theory and geodesic theory, four types of domes(helical winding, helical winding ellipsoid, polar winding, polar winding ellipsoid)were studied.The control equations of each type of dome were derived.According to each type of dome, case calculation was carried out to verify the correctness of the design method.The result analysis shows that the design results of meridian, winding angle, wall thickness, fiber stress and pV/W of the same winding pattern are similar.Ellipsoid dome is recommended to avoid the curvature inflection point of meridian, which is also conducive to processing and manufacturing.The research results can provide reference for the design and selection of FCPV.
