THICKNESS FLUCTUATION ANALYZING ROTOR, AND ROTOR THICKNESS FLUCTUATION GENERATION DEVICE USING IT

PROBLEM TO BE SOLVED: To provide a thickness fluctuation analyzing rotor used for analyzing thickness fluctuation of a disc brake. SOLUTION: This thickness fluctuation analyzing rotor R has unit block bodies each comprising plates 4 facing each other, and actuators 5 interlaid between the plates, and is composed by arranging the plurality of unit block bodies on the same plane, and connecting the plates of the unit block bodies adjacent to each other by a flexible material. The actuator 5 constituting the unit block is provided for each of the plates facing each other, and a rotor board is arranged between the respective actuators. By using the thickness fluctuation analyzing rotor, hydraulic pressure fluctuation ΔP on a thickness fluctuation basis of the rotor is easily measured in a test on a bench stand without using a dynamo facility.
