环肋圆柱壳是工程实际中一种常见的结构形式,是船舶、飞机、压力容器和管道的基本结构,在船舶行业、航空航天、化学工业等都有非常广泛的应用.非均匀环肋圆柱壳是环肋圆柱壳的一种结构形式,主要表现在肋距分布、肋骨大小的不均匀.非均匀环肋圆柱壳对加强局部强度,改善圆柱壳的振动性能等都有很大的作用.
本文用环肋圆柱壳模拟潜艇耐压船体结构,其主要承受深水压力,因此要保证其安全性,有必要对环肋圆柱壳进行强度、稳定性的校核.同时为了提高潜艇水下航行时的隐蔽性,有必要对环肋圆柱壳进行模态和谐响应分析,求出环肋圆柱壳的固有振动频率和径向均方速度.本文主要是利用有限元分析软件ANSYS对五种环肋圆柱壳进行建模并进行静、动态性能分析,得到环肋圆柱壳的应力、失稳临界压力、固有频率和径向均方速度,并对结果进行比较.

Ring-stiffened cylindrical shell is a common structural form in engineering. It is the basic structure in ship, aircraft, pressure vessels and piping. It has been widely used in the shipbuilding industry, aerospace, chemical industry. Non-uniform ring-stiffened cylindrical shell is one of the ring-stiffened cylindrical shell, it has different frame spacing and rib types. To strengthen local strength, improve vibration performance of cylindrical shell, non-uniform ring-stiffened cylindrical shell has a significant role.
The ring-stiffened cylindrical shell is used to imitate the pressure hull of submarine structure, it mainly bear the tremendous pressure in deepwater. The structure must be assured to meet the demands of safety in utilization. So, it is necessary to check the strength and stability of the pressure hull. Meanwhile, in order to improve the hiding ability of the submarine structure, the characteristics of modal and harmonic of the ring-stiffened cylindrical shells should be analyzed, find the natural frequency and the radial quadratic velocity of the shells. In the paper, we use the finite element analysis software ANSYS to create the calculation model and do the analysis of the characteristics of static and dynamic of shell. Get the stress and critical pressure, natural frequency and radial quadratic velocity, and compare with the results.
