基于偏好聚合不精确法的湿式制动器稳健设计

Wet Brakes Robust Design Baeing Preference Aggregation Method of Imprecision

针对不确定性对产品性能的影响,以湿式多盘制动器设计为例,利用响应面模型,建立了设计变量和制动性能的关系。根据不精确法,采用整体偏好聚合函数,将随机、模糊、未确知三种不确定性对系统性能均值和波动性的影响综合起来考虑,改善了传统稳健设计的线性加权和法的缺陷。

According to the effect of non-deterministic parameters on product performance, with wet multi disc brake, the functional relationship between design variable and brake performance was proposed by the response surface method, based on method of imprecision and adopting overall preference aggregation function, the three uncertainties, namelyrandom, fuzzy and unknown, which affect means and fluctuation of the system performance, would be taken into account for improving the traditional robust designs linear weighted sum method.
