基于有限质点法和代理模型的加筋箱梁结构筋板尺寸优化
摘要
Abstract
To optimize the size of stiffened box girder structure,in this paper,the finite particle method was used to analyze the buckling of the structure directly without building stiffness matrix,and then the global search strategy based on Pan-Kriging proxy model and multi-island genetic algorithm was used to optimize the size of stiffened plate,thus saving the time of numerical calculation while ensuring the analysis accuracy.Finally,taking a box girder segment subjected to one-way bending as an example,the buckling analysis and size optimization design were carried out.The comparison with the original model shows that the goal of improving the bearing capacity can be achieved with good convergence and low time cost,which verifies the reliability of the proposed optimization method.关键词
