Abstract
This paper presents computational techniques for the analysis of rotating machinery. The modeling of the dynamical behavior of these machines needs to account for various effects, some of which are related to parameters with a significant amount of uncertainty. The work can be divided into three main parts: The first part describes the numerical assembly technique (NAT). NAT is a modelling technique which provides (semi-)analytical solutions for the equations of motion of slender structures, such as a shaft of an electrical machine. The second part then applies this model in combination with measured frequency response functions, in order to find suitable values material parameters. In the third part, the model and appropriate material parameters are used for balancing the rotor. The proposed balancing technique uses the measured response of the rotor but does not need trail weights for the balancing procedure.
