Mechanical vibration -- Evaluation of machine vibration by measurements on non-rotating parts -- Part 4: Gas turbine sets with fluid-film bearings
This standard was last reviewed and confirmed* in 2015.
ISO 10816-4:2009 establishes specific provisions for evaluating the severity of in-situ, broad-band vibration measured radial (i.e. transverse) to the shaft axis on all main bearing housings or pedestals and in the axial direction on thrust bearings. These are in terms of:
- vibration under normal steady-state operating conditions;
- vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes;
- changes in vibration which can occur during normal steady-state operation.
ISO 10816-4:2009 is applicable to heavy-duty gas turbine sets used in electrical and mechanical drive applications, with fluid-film bearings, outputs greater than 3 MW and an operating speed range under load between 3 000 r/min and 30 000 r/min.
