Turbine blade fatigue monitor
Patent
·
OSTI ID:6493885
This patent describes a vibratory fatigue measuring apparatus for measuring fatigue in equipment including a turbine rotor having turbine blades. It comprises: sensor means for generating a displacement signal indicating displacement of the turbine blades caused by vibration generated during normal operation of the equipment. The sensor means including at least two sensors positioned outside a path taken by the turbine blades and fatigue accumulation means for calculating fatigue usage in the turbine rotor in dependence upon the displacement signal.
