Abstract: Two methods of high accuracy testing of eccentric mass of huge rotors are proposed. Based on the principle of hydrostatic bearing, the new equipment can support a rotor as heavy as hundreds of tons while keeps it in a floating state. Therefore, the influence of friction is eliminated. Two kinds of structures of the equipment are introduced with the comparison of their advantages and disadvantages. Experiments show that the new equipment an reach high accuracy as well as high feasibility of engineering achievement.
