... frequency range as well. It is concluded that the mode superposition method is preferable to the Guyan reduction method for mechanical systems, such as turbo generator units, that operate over a wide speed range.

... compared. Results show that the proposed techniques gives models with a reduced number of degrees of freedom and at the same time good accuracy in temperature calculation. The reduced models are then suitable for real time computation. model reduction life monitoring thermal stress turbine...
