Scope
GB/T 28784.3-2012 is the English-translated version of 机械振动 船舶振动测量 第3部分：船上设备安装前的振动测量.
GB/T 28784.3-2012 is the Chinese standard "Mechanical vibration -- Measurement of vibration on ships -- Part 3: Pre-installation vibration measurement of shipboard equipment".
Its scope clause reads: This section GB/T 28784 specifies the different types of vibration generated by the equipment on board (the structural vibration noise in the form of a ship knot Configuration pass) measurement guidelines, requirements and procedures, the measuring device is factory acceptance test (FactoryAcceptanceTest, FAT) a part of.
This part of the operation and installation conditions have a clear measurement device is described in detail, for example, test bench at the supplier's. This section provides a typical test results framework standards for passenger ships, merchant ships, yachts, equipment on board high speed craft on.
Due to the rotational direction of vibration of the structure contribute little noise, vibration involves only part of the translation direction, but does not specify equipment vibration or knot Structure noise limits. Its clauses include terms and definitions.

This section GB/T 28784 specifies the different types of vibration generated by the equipment on board (the structural vibration noise in the form of a ship knot
Configuration pass) measurement guidelines, requirements and procedures, the measuring device is factory acceptance test (FactoryAcceptanceTest, FAT) a part of. This part of the operation and installation conditions have a clear measurement device is described in detail, for example, test bench at the supplier's.
This section provides a typical test results framework standards for passenger ships, merchant ships, yachts, equipment on board high speed craft on.
Due to the rotational direction of vibration of the structure contribute little noise, vibration involves only part of the translation direction, but does not specify equipment vibration or knot
Structure noise limits.
