适用范围：This standard provides specific guidance for assessing the severity of radial vibration measured on the bearing housings of gas turbines with fluid-film bearings in situ. The criteria provided in this document apply to heavy-duty gas turbine sets used in electrical and mechanical drive applications, with outputs greater than 3 MW and a speed range under load between 3 000 r/min and 30 000 r/min. This includes gas turbines coupled to other rotating machinery either directly or through a gearbox. Two criteria are provided for assessing the machine vibration when operating under steady state conditions. One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude. In addition, different criteria are provided for transient operating conditions, such as run-up and coast-down. The evaluation procedures presented in this part of ISO 10816 are based on broad-band measurements. This part of ISO 10816 is not applicable to the following: a) aero-derivative gas turbines (including gas turbines with dynamic properties similar to those of aero-derivatives); b) gas turbines with outputs greater than 40 MW and with rated speeds of 1500 r/min, 1800 r/min, 3000 r/min or 3600 r/min (see ISO 20816-2); c) gas turbines with outputs less than or equal to 3 MW (see ISO 10816-3); d) gas turbine driven rotodynamic pumps (see ISO 10816-7); e) coupled steam turbines and/or generators with outputs less than or equal to 40 MW (see ISO 10816-3); f) coupled steam turbines and/or generators with outputs greater than 40 MW and speeds of 1500 r/min, 1800 r/min, 3000 r/min or 3600 r/min (see ISO 20816-2); g) coupled steam turbines and/or generators with outputs greater than 40 MW and speeds other than 1500 r/min, 1800 r/min, 3000 r/min or 3600 r/min (although generators seldom fall into this category) (see ISO 10816-3); h) synchronizing clutches which couple the gas turbine to a steam turbine or generator (see ISO 20816-2); i) coupled rotary compressor
