摘　　要：箱型结构内部加强筋布局及支撑位置对结构性能有重要影响。提出一种箱型结构加强筋分布及支撑位置协同优化设计方法,引入独立的支撑单元和加强筋基结构,建立箱型结构加强筋和支撑位置协同优化数学模型。通过自适应成长法对箱型结构进行加强筋优化设计,基于双向渐近结构优化方法对支撑位置进行优化,得到最优的加强筋分布和支撑位置。结果表明,相比于已知支撑位置的加强筋优化设计,协同优化得到的支撑位置和加强筋分布具有更优的力学性能。The internal stiffener layout and support location of housing structure played an important role in improving of structural performance and lightweight.A design method for hybrid distribution optimization of stiffener and support locations of housing structures was proposed.Independent support elements and stiffener base structures were introduced to establish a mathematical model for the hybrid optimization of stiffener distribution and support location of the housing structure.The optimal design for stiffener distribution of the housing structure was performed by an adaptive growth method.The support location was optimized based on the bi-directional evolutionary structural optimization method.The results show that the support locations and distribution of stiffeners obtained from the hybrid optimization have better mechanics properties than the optimized results of the housing structure with known support locations.
