对几种性能较好的汽车半金属刹车材料的综合性能(包括性能价格比)进行了模糊优化评判.优选出了一种性价比高的材料,同时,试验表明,使用性能较好的材料,并不一定综合性价比高. The comprehensive performance (including the cost performance) of several semi-metallic brake materials with good performance is evaluated by fuzzy optimization, and a material with high cost performance is selected. At the same time, the test shows that the material with better performance Not necessarily integrated cost-effective.
