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%...

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 pipelines a multi-objective robust design method based on satisfaction function was proposed combining with Taguchi robust design approach, This method converted the signal-to-noise ratio of the product quality characteristics to the degree of satisfaction which had the larger- better characteristics of Taguchi robust design. and the multi-objective ro...
