DEVICE AND METHOD FOR MEASURING CENTER OF GRAVITY AND MOMENT OF INERTIA

摘要

PURPOSE: A device for measuring a center of gravity and a moment of inertia and a method for measuring the center of gravity and the moment of inertia using the same are provided to reduce manufacturing costs and to simplifying a structure by measuring a center of gravity and a moment of inertia with one device without moving or installing a measurement object. CONSTITUTION: A device for measuring a center of gravity and a moment of inertia comprises a measuring table(110), a first shaft(120), a second shaft(140), a pivot(150), a bearing(160), a force sensor(170), a fixing unit(180), and a driving unit(190). The measuring table supports measurement objects. The pivot supports the second shaft to be pivotable so that the first and second shafts are inclined by an offset of a center of gravity of the measurement objects. The bearing is installed in the outer circumference of the first shaft so that the first shaft is relatively rotated and supports a moment generated caused by the first and second shafts being inclined. The force sensor supports the bottom surface of the bearing and measures a reaction force with respect to the bearing generated caused by the first and second shafts being inclined. The driving unit generates torsion in a torsion bar by rotating the first shaft when the second shaft is fixed.
