The paper presents a simulation method, which helps to optimize the rotor design in terms of vibration and production costs. The method is particularly suitable for rotors that run close below or above the first bending critical speed, because a single-sided rotor core eccentricity excites this first bending mode very strongly. This simulation method can be used to optimize the rotor design to avoid elastic balancing. Rigid balancing can be used, even if the rotor runs above the first critical bending speed. Additionally, this method helps to find the tolerable residual unbalance and maximum tolerable limit for a single-sided rotor core eccentricity. Therefore the method helps to optimize the production process by avoiding elastic balancing and machining of the rotor core outer diameter.
