This paper deals with development of balance measurement equipment for medium size rotor. A prototype of the balance measurement system was developed by Tokai Techno Co. However, it couldn't realize the satisfied measurement accuracy on unbalance quantity and its position, because it has several problems in the system structure. In the study in last year, it was revealed that the operational frequency is close to the natural frequency of the stiffness plate for the bending mode and the resonance between the system consisted of the stiffness plate and the main shift, and the operation motion makes large influence to the unbalance measurement. In this study, the dynamic characteristics of the balance measurement equipment was estimated by operation experiment and simulation by FEM analysis. Change of the shape or mass on the measurement object gives to the dynamic characteristics, were estimated by the simulation of FEM model. The influence of damping of spring plate was also estimated and it became obvious that the combination of changes on the system parameters could make the balance measurement system higher performance machine.
