建立了碳化硅、石墨颗粒混杂增强铝基复合材料的摩擦系数模型。将混杂复合材料摩擦系数处理成无碳化硅时的石墨 -铝基复合材料摩擦系数分量、碳化硅对钢的刮擦从而引起的摩擦系数分量两部分之和。对两部分分量分别进行了建模和计算 ,然后相加得到混杂复合材料的总摩擦系数模型。通过与实验数据的比较 ,表明该模型能够较准确地计算较高石墨含量的混杂铝基复合材料的摩擦系数。
The friction coefficient model of aluminum matrix composite reinforced with silicon carbide and graphite particles was established. The friction coefficient of hybrid composite material processed into silicon carbide-free graphite-aluminum composite friction coefficient component, silicon carbide scratching the resulting friction coefficient component of the sum of the two parts. The two components are respectively modeled and calculated, and then the total friction coefficient model of the hybrid composite is obtained. The comparison with the experimental data shows that the model can calculate the friction coefficient of the hybrid graphite matrix composites with higher graphite content.
