将满意函数与田口鲁棒性相结合，提出了一种基于满意函数的多目标鲁棒设计方法，以解决易受噪声因素干扰的多目标优化问题。该方法将产品质量特性的信噪比转化为田口稳健设计的期望越小越好，通过加权几何平均实现多目标稳健设计，从而解决了易受噪声因素影响的多目标优化问题。通过建立旋转护栏的LS-DYNA有限元模型，在不改变旋转护栏基本尺寸的前提下，对旋转护栏进行多目标稳健设计，以解决新型旋转护栏截面参数不确定的多目标优化设计问题。结果表明，新型旋转护栏筒的稳健性设计能够抵抗噪声的干扰，结构更加稳健，符合相关法规，实现了新型旋转护栏轻量化的目的。研究结果对提高新型旋转护栏的鲁棒性具有一定的理论和工程意义。
In this paper, a multi-objective robust design method based on satisfaction function was proposed by combining satisfaction function with Taguchi robust to solve the multi-objective optimization problem, which was easily interfered by noise factor. This method converted the signal-to-noise ratio of product quality characteristics into the expected smaller-the-better of Taguchi robust design, and realized the multi-objective robust design by weighted geometric mean, so as to solve the multi-objective optimization problem easily affected by noise factors. Under the premise of without changing rotate barrel of basic size by LS-DYNA FE model of rotary guardrail, the proposed method was carried out on the rotate barrel of multi-objective robust design, in order to solve the new rotary guardrail section parameter uncertain multi-objective optimization design. The results showed that the robust design of the new rotate barrel could resist the interference of the noise, the structure was more robust, and it conformed to the relevant laws and regulations by which was realized the purpose of lightweight of the new rotary guardrail. The research results had certain theoretical and engineering significance in improving the robustness of the new rotary guardrail.
