摘　　要：为提高结构优化设计效率,基于克里金代理模型并结合自动化仿真技术提出了一种结构优化设计方法。该方法使用Isight软件搭建优化框架,实现自动化数值模拟和数据提取,得到基础数据后构建代理模型,最后使用优化算法对搭建的代理模型实现多目标优化分析。为验证其有效性,以船舶板架结构优化为例,分析设计变量对板架结构响应的影响,对比代理模型优化结果与有限元数值模拟结果表明,针对船舶板架结构优化的代理模型具有良好的可靠性,能有效替代仿真结果,提高结构优化计算效率。In order to enhance the efficiency of structural optimization design,a structural optimization design method based on the Kriging surrogate model and automated simulation is proposed.This method utilizes Isight software to construct an optimization framework,enabling automated numerical simulation calculations and data extraction.Utilizing foundational data,a surrogate model is constructed,and finally,optimization algorithms are employed to conduct multi-objective optimization analysis on the constructed surrogate model.To validate its effectiveness,ship hull frame structural optimization is taken as an example to analyze the influence of design variables on the response of the frame structure and compare the optimization results of the surrogate model with the results of finite element numerical simulation.The results indicate that the surrogate model exhibits good computational performance for ship hull frame structural optimization problems,it can effectively replace simulation results,thereby improving optimization computational efficiency.
