本文提出了一种新的、有效的板壳结构加劲肋最小柔度布局的生成方法--自适应增长法。该方法基于自然界中分支系统的自适应生长规律，即分支自动向能够提高全局功能性能的方向生长和分支自动向能够提高全局功能性能的方向生长，例如最大限度地吸收阳光或水。如果加强筋的延伸遵循与自然界中的分支系统相似的自适应生长和分支规则，则板或壳结构可以获得良好的力学性能。加劲肋从所谓的种子开始，朝着具有最大整体力学性能的方向生长和分支，这取决于当前结构的设计灵敏度。在生长过程中，控制体积增量，以便能够产生新的分支和消除退化分支。通过典型的加筋板布局设计问题验证了所提方法的正确性和有效性。
A new and effective generation method for the stiffener layout pattern for plate and shell structures to achieve minimum compliance, the so-called adaptive growth technique, is suggested in this paper. The method is based on the adaptive growth rule of branch systems in nature that branches grow and branch off automatically towards such directions that can improve the global functional performance, such as the maximum absorption of sunlight or water. It is expected that a plate or shell structure can achieve good mechanical performance if the stiffeners extend by obeying a similar adaptive growing and branching rule as branch systems in nature. The stiffeners, starting from the so-called seeds, grow and branch off towards the direction with the maximum effectiveness of the global mechanical performance, which is dependent on the design sensitivity of the current structure. During the growth process, the volume increment is controlled so as to make it possible to create new branches and to eliminate degenerate branches. The validity and effectiveness of the suggested method are confirmed by some typical stiffener layout design problems.
