摘要
新型逃生管道参数具有不确定性且单目标优化存在局限性,为了实现新型逃生管道多目标稳健性设计,结合田口稳健性设计方法与满意度函数,提出了一种基于满意度函数的多目标稳健性设计方法。该方法将产品质量特性的信噪比转换为具有田口稳健性设计的望大特性的满意度,然后通过加权几何均值实现结构的多目标稳健性设计。通过使用Hypermesh和LS-DYNA建立新型逃生管道的有限元模型,并对该有限元模型进行验证,然后运用所提出的方法对新型逃生管道进行多目标稳健性设计。结果表明,稳健性设计后新型逃生管道的信噪比提升了5.3%,说明管道抵抗噪声因子的干扰能力增强,结构更稳健;新型逃生管道质量降低了9.6%,实现了管道轻量化的目的。研究结果对提高新型逃生管道的稳健性具有一定的理论和工程意义。
There are some uncertainties in the parameters of the new escape pipeline and the single-objective optimization has its limitations.To realize the multi-objective robust design of the new escape pipeline,a multi-objective robust design method based on satisfaction function was proposed combining with Taguchi robust design approach.This method converted the signal-tonoise ratio of the product quality characteristics to the degree of satisfaction which had the largerbetter characteristics of Taguchi robust design,and the multi-objective robust design of the structure was realized by weighted geometric mean.The finite element model of the new escape pipeline was established and verified by using Hypermesh and LS-DYNA,and then the proposed method was applied to the multi-objective robust design of the new escape pipe.The results showed that the signal-to-noise ratio of the new escape pipe after the robust design was increased by 5.3%,the ability of pipeline to resist noise factor interference was enhanced,and the structure was more robust.The weight of the new escape pipeline was reduced by 9.6%,and the purpose of pipeline lightweight was achieved.The research results have certain theoretical and engineering significance for improving the robustness of the new escape pipeline.
