Wykorzystanie eksperymentalnej oraz numerycznej analizy modalnej w badaniach i symulacji dynamiki stojanów maszyn elektrycznych dużej mocy

The paper presents application of two methods of dynamic characteristics assessment for case of high power electric machines. First method uses modal experiment to identify normal modes and related mode shapes. Second one is numerical calculation based on Finite Element Method. Numerical model parameters were estimated basing on test data with using optimization methods based on genetic algorithms. The aim of the project was creation of effective method for assessment and modification of high power electric machines stators dynamics characteristics.
