摘要
结合试验设计、Kriging近似建模技术、Monte Carlo模拟技术,对多种截面薄壁结构进行了确定性优化,并构造了基于6σ鲁棒性分析的优化方法。研究结果表明:实现了对薄壁结构的抗弯吸能特性的优化,并提高了产品质量的可靠性。
The thin-walled structure of different sections was optimized through the applications of DOE and Kriging approximate modeling and Monte Carlo simulation techniques, and an optimization method was constructed based on 6~ robustness analysis. The results show that the optimization in bending energy absorbing ability is realized and the robustness of thin-walled structure＇s quality is imoroved.
