    摘要:

    摘要: 耐压舱体是水下系统不可或缺的一部分,既要承载内部设备,又要承受外部压力,其强度至关重要。当舱体的加强筋板并非环肋时,筋板的设计只能凭设计师的经验完成,再进行仿真验证,这大幅增加了研发成本。本文采用基于SIMP插值的变密度拓扑优化方法,求解了耐压舱体在外压作用下的传力路径,并以此为依据优化了舱壁上加强筋的布置。经计算,优化后的舱体模型最大应力减小到了材料的许用范围内,并且变形量大幅减小,说明该拓扑优化方法在筋板设计上具有一定的指导意义。

    Abstract:

    Abstract:The pressure-resistant cabin is an indispensable part of the underwater system. It needs to bear both internal equipment and external pressure, and its strength is very important. When the stiffeners of the cabin body are not ring ribs, the design of the stiffeners can only be completed by the experience of the designer and then verified by simulation, which greatly increases the research and development cost. In this paper, the variable density topology optimization method based on SIMP interpolation is used to solve the force transmission path of the pressure cabin under external pressure, and based on this, the arrangement of stiffeners on the bulkhead is optimized.By calculation, the maximum stress of the optimized cabin model is reduced to the allowable range of materials, and the deformation is greatly reduced, indicating that the topology optimization method has a certain guiding significance in the design of reinforcement plates.
