摘要
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。
A model of friction coefficient of aluminum matrix hybrid composite was proposed. The total friction coefficient of the hybrid composite was treated as the sum of two parts. One part is the friction coefficient of the graphite aluminum matrix composite without consideration of silicon carbide. The other part is that resulted from silicon carbide ploughing steel. The first part was described by a regression equation using an exponential function. The second part can be induced from the classic friction theory of molecular mechanics. The model of friction coefficient of the hybrid composite is proved to be very suitable to calculating the friction coefficient of the hybrid composite with high fraction of graphite. [
