Earthquake Dynamics of Turbine Rotors Considering Their Foundations

Popis výsledku v původním jazyce

Various rotating systems can be efficiently analyzed using multibody approaches. Especially in the case of a combination of rotating and non-rotating (stator) components, which needs to consider bodies with different inertia effects. On the other hand, power plants (in particular nuclear power plants) have to be carefully designed with respect to various undesirable problems and phenomena, which also include a seismic excitation. This paper deals with the dynamics of large turbine rotors common in power plants including the effects of a moving foundation and stator parts. The whole turboset system can be divided into two basic parts – a foundation including all stator (non-rotating) components of a turbine and a rotor train. A mathematical model is based on the system division into a rotor train and a non-rotating foundation part were created. An in-house software was developed based on the proposed modelling methodology and its performance is demonstrated by means of the particular real turbine example. Results of both mentioned strategies for the mathematical model solution are compared. In: Abstract Book of The 9th Asian Conference on Multibody System Dynamics ACMD 2018, Shanghai Jiao Tong University, Xi'an (China), pp. 130-131, August 2018.
