6、························⋯⋯14GB/T11348.1-1999前言本标准是旋转机械转轴径向振动测量和评定系列标准的第1部分。该系列标准总题目为“旋转机械转轴径向振动的测t和评定”，它由以下各部分组成:第1部分:总则第2部分:陆地安装的大型汽轮发电机组第3部分:辐合的工业机器第4部分:燃气轮机组第5部分:水力发电厂和泵站机组本标准等同采用ISO7919-1:1996《非往复式机器的机械振动在旋转轴上的侧t和评价准则第1部分:总则》。本标准是对GB/T11348.1-1989《旋转机械转轴径向振动的测量和评定第一部分总则》进行的修订。本标准与GB/

7、T11348.1-1989相比，主要技术内容改变如下:1.本标准表述的准则须由GB/T6075.1-1999中规定的对非旋转部件振动的评定准则来补充。如果两项标准的方法都可使用，通常应使用限制更严的那一项2.本标准不对仪器测量系统误差提出定量的要求。3.本标准增加了用于评定振动的振动值的变化准则。4.本标准增加了对机器设定运行振动限值的技术内容。5，本标准增加了振动变化的矢量分析，该部分内容作为附录D.本标准自实施之日起代替GB/T11348.1-1989,本标准的附录A是标准的附录。本标准的附录B、附录C,附录D、附录E都是提示的附录。
