The calculation formulae of temperature field and thermal stress field in a steam turbine rotor, when varying rate of steam temperature is changed in series, are derived with integral transform methods. The formulae can be used directly in thermal stress monitering of rotor. The rate of data management is fast with analytics, as compared with finite difference methods, and therefor, fast monitoring of rotor can be performed.
