摘　　要：综述了机械摩擦过程中摩擦力、摩擦热和摩擦振动噪声等摩擦状态特征量的监测方法与研究现状。阐述了摩擦力的产生机理及影响因素,重点表述了摩擦力的监测方法——直接法和间接法;总结了研究摩擦热的解析法和有限元法等理论方法,着重表述了摩擦过程中摩擦温度的监测技术--直接测温和间接测温法;简述了摩擦振动的机理,重点归纳了摩擦振动特征量的提取方法——时域法、频域法和时频法等;简介了摩擦噪声机理及特性,结合摩擦振动表述了摩擦噪声监测方法;指出了多摩擦特征监测和综合监测为机械摩擦过程状态监测的未来发展趋势。The monitoring methods and research status of friction, frictional heat and frictional vibration and noise in mechanical frictional process were discussed. The mechanism and influencing factors of friction were explained and the presentation focused on the frictional monitoring methods： direct and indirect methods. The theoretical study of analytical and finite element methods was summarized, and the monitoring methods in frictional temperature were emphatically expressed： direct and indirect thermome- try. The mechanism of frictional vibration was stated, and the extraction of frictional vibration characteristics was emphatically summed up ： time domain, frequency domain method and the time-frequency method. The mechanism of frictional noise was intro- duced, and the monitoring method of the frictional noise with vibration was described. The future trends of multi-feature and inte- grated monitoring in mechanical frictional process were pointed out.
