摘　　要：生活在深海的维纳斯花篮结构具有质量轻、强度高和承压性能好等特性,是一类典型的轻质高强生物结构。本文仿维纳斯花篮的特殊构型,提出了一种水下耐压壳体结构设计方案,并进行了耐压性能数值仿真研究。以240 mm舱段为标准,在保证体积、长度、外径和施加外水压均相同的情况下,对比分析了常规水下航行器壳体结构、两种对角加固壳体结构和仿维纳斯花篮壳体结构的耐压性能,结果表明,仿维纳斯花篮结构具有最佳的强度性能,其最大应力和主体应力最小。本文提出的仿生结构对于水下航行器的创新设计具有重要意义。The structure of a Venus flower basket,which lives in the deep sea,has characteristics such as light weight,high strength,good pressure resistance,making it a kind of typical lightweight and high-strength biological structure.In this paper,we propose a pressure-resistant shell structure design inspired by the structure of a Venus Flower Basket and conduct a numerical simulation study on its pressure resistance performance.Using the 240 mm compartment section as the standard,under the condition of the same volume,length,outer diameter,and external water pressure,the pressure resistant performance of conventional underwater vehicle shell structures,two diagonal reinforced shell structures,and the Venus flower basket-inspired shell structure are compared and analyzed.The results show that the Venus flower basket-inspired structure has the best strength performance,with the smallest maximum stress and principal stress.The proposed biomimetic structure is of great significance for innovative design of underwater vehicles.
