Title:
RIGID BODY PROPERTY IDENTIFICATION DEVICE AND RIGID BODY PROPERTY IDENTIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/005114
Kind Code:
A1
Abstract:
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 is provided with a stationary part (10) which is immovable, a movable part (20) which is movable with respect to the stationary part and includes the object to be measured (T), a support means (30) which supports the movable part so that the movable part can freely vibrate with respect to the stationary part, a measurement means (40) which measures data required to calculate the natural frequency of the movable part when the movable part vibrates, and an analysis means (50) to which conditions for support by the support means and measurement data measured by the measurement means are inputted and which performs arithmetic processing on the basis of the conditions for support and the natural frequency calculated from the measurement data. The analysis means identifies the rigid body properties of the object to be measured on the basis of the conditions for support by the support means and the natural frequency calculated from the measurement data. Consequently, the 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 is provided.
