１．振动诊断标准 （ｌ）振动绝对标准 在状态监测和简易诊断中采用已公布的振动评价标准。表１为常见的几种机械产品的振动评价标准；表２则以振动烈度（速度）值为判别标准；表３是加拿大采用的设备振动维护标准，即以轴承振动测量值为判别标准；表４是国际标准ＩＳＯ １０８ 1. Vibration Diagnostic Standard (l) Vibration Absolute Standard The published vibration evaluation standards are used for condition monitoring and simple diagnosis. Table 1 for several common mechanical vibration evaluation criteria; Table 2 vibration severity (speed) value as a criterion; Table 3 is the Canadian equipment vibration maintenance standards, that the bearing vibration measurement as a criterion; Table 4 is the international standard ISO 108
