摘要: 论述了声发射技术应用于滚动轴承状态监测和故障诊断的方法。对各典型状态滚动轴承在不同转速和载荷下的声发射信号进行了振动分析,研究了滚动轴承的损伤振动随转速和载荷的变化规律。定义了基于振动分析的声发射信号特征参数,研究了各特征参数随转速、载荷和损伤类型的变化规律。研究结果为滚动轴承的安全运行、状态监测和故障诊断提供了一种新的方法。Abstract: The AE technique is a very functional and valid technique applied on rolling element bearings diagnosis and examination. Based on the vibration analysis of AE signals under varying load and rotating speed, the patterns of damage vibration of rolling element bearings under varying load and rotating speed were researched. The characteristic parameters of AE which were defined based on vibration analysis under varying load, rotating speed and damage type were also studied. The results provided a new technique for security running, condition monitoring, and fault diagnosis of rolling element bearings.
