RIGID BODY PROPERTY IDENTIFICATION DEVICE AND RIGID BODY PROPERTY IDENTIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a rigid body property identification device or a rigid body property identification method capable of identifying rigid body properties with high accuracy while reducing the number of measurement points.

SOLUTION: A rigid body property identification device for identifying rigid body properties including the mass and the position of center of gravity of an object to be measured comprises: a stationary part 10 which is immovable; a movable part 20 which is movable relative to the stationary part and includes an object to be measured T; support means 30 which supports the movable part so that the movable part can freely vibrate relative to the stationary part; measurement means 40 which measures data required to calculate the natural frequency of the movable part when the movable part vibrates; and analysis means 50 to which support conditions by the support means and measurement data measured by the measurement means are inputted and which performs arithmetic processing based on the support conditions and the natural frequency calculated from the measurement data. The analysis means identifies the rigid body properties of the object to be measured based on the support conditions by the support means and the natural frequency calculated from the measurement data.
