摘　　要：通过分析固体表面接触特性,得知摩擦力矩传递是由摩擦面的少数微凸体承担,它们承受的应力和热量为平均应力和热量的几十倍以上:分析摩擦片的冷却机理发现,现行的摩擦片冷却思路有缺陷.在此基础上,依据笔者提出的功能型摩擦材料概念和功能化处理技术,对新型坦克摩擦片进行功能化处理,使之转化成功能型摩擦材料.并利用物理模型,分析功能型摩擦材料自我调节摩擦面的热量分布,防止摩擦面局部区域温度过高的功能机理.坦克传动系统国防科技重点实验室台架试验表明,摩擦片经功能化处理后,摩擦性能保持不变,耐热性能提高50%,耐磨性能提高近3倍.By analyzing the surface properties of solid, it is known that the transmission of friction torque is undertaken by micro-protuberances on the friction surface. The stress and heat applied on them are decade times of average stress and heat. After analyzing cooling mechanism of friction discs, it is found that the existing cooling idea is defective. According to the conception of function friction material and function treatment technique advanced by the authors, the new type tank friction discs was treated in order to transmit them into function friction material. And as this was done, the friction properties remained unchanged, heat-proof properties increased about 50% and wear-proof properties increased 3 times.
