Foundation dynamics of the steam turbine generator

U ovom se radu nakon uvoda u teorijske osnove vibracija, vibracijskih sustava i temelja odabire okvirni temelj za parno-turbinski agregat od 250 tona čiju je dinamiku potrebno analizirati. Temelj se potom 3D modelira u programskom paketu Catia V5R20 i modalno analizira u programskim paketima ANSYS R17 i FEMAP. Rezultati modalne analize indiciraju da vibracijski sustav temelja i parno-turbinskog agregata ima takve vibracijske karakteristike koje neće imati problema s rezonancijom.This research features an introduction to vibration theory basics, vibrational systems and foundations, after which a frame-type foundation is selected as the most suitable for the steam turbine – generator system weighing 250 tons. The foundation system is then modelled in Catia V5R20 and modally analysed in ANSYS R17 as well as FEMAP. The results of modal analysis indicate that there is no concern of resonance between the steam turbine system and the foundation system
