黄金分割法是一维空间搜索最佳值的优化方法。将黄金分割序列与摩擦材料配方中组分的体积分数关联,可以设计和计算摩擦材料配方。摩擦材料配方优化分3步进行:(1)将原材料分为纤维增强体组、填料组和树脂基体组,考察纤维增强体组和填料组中的各个组分对摩擦性能的影响;(2)固定树脂基体组的体积分数,优化纤维增强体组和填料组的含量;(3)优化树脂基体组的含量。
Golden section approach is an optimization method for one dimension space. By correlating golden section sequence and volume fraction of raw materials used, friction material formulations can be designed and calcula- ted. The optimized formulation can be obtained by three phases: (1) effect of each ingredient on friction performance, (2) optimization of volume fraction of fibers group and fillers group, (3) optimization of volume fraction of binders group.
