CFRP缠绕周向内波纹耐压壳铺层优化设计

Optimized CFRP layering design for circumferential internal corrugated compression shell

    摘要
  • 摘要:
    目的 为顺应深海潜航器耐压壳结构轻量化、高强度的发展趋势，提出碳纤维复合材料（CFRP）缠绕铝合金周向内波纹耐压壳的结构增强方法，并对其CFRP铺层方式进行优化设计分析。
    方法 利用ABAQUS有限元仿真软件，通过改变CFRP铺层参数，根据复合材料层的层间应力分布情况，探究14层CFRP铺层下最佳缠绕角度，进而获得最佳铺层方式。并结合相关强度失效准则，对其强度进行校核。
    结果 研究结果表明：CFRP增强周向内波纹耐压壳最优缠绕角度为40°，在铺层方式为（±40° 2/±55° 2/±70° 2/90° 2）时，层间应力分布较为均匀。该结构的强度满足实际使用需求，且其质量更轻。
    结论 该结构可减轻深海耐压壳整体质量，推动深海耐压壳设计向轻量化方向发展。

     

    Abstract:
    Objective In order to meet the development trend of low weight and high strength in the design of compression shell structures for deep-sea submersibles, this paper proposes a structural enhancement method which involves winding a circumferential internal corrugated compression shell with a carbon fiber reinforced polymer (CFRP), then analyzes and optimizes the CFRP layering scheme.
    Method Finite element simulation software ABAQUS is used to change the layering parameters of the CFRP according to the stress distribution of the composite layers, and the optimal winding angle under 14 layers of CFRP is explored to obtain the best layering scheme. The relevant strength failure criteria are then combined to check the intensity.
    Results The results indicate that 40° is the best CFRP winding angle to enhance the circumferential internal corrugated compression shell. When the layering mode is (±40°2/±55°2/±70°2/90°2), the stress distribution between the layers is relatively uniform, meaning that the structure has a lighter weight while its strength fulfills the actual use requirements.
    Conclusion The proposed structure can reduce the overall weight of deep-sea compression shells and push the development of the field toward lightweight design.
