MEASURING DEVICE OF CROSS-INERTIA-PRODUCT IN LIMITED ANGULAR ROTARY SHAFT AND MEASURING METHOD THEREOF

摘要

PURPOSE: An apparatus and a method for measuring a cross inertia moment of a limit rotating shaft is provided to minimize an interference due to the cross inertia moment in a sight stabilization system. CONSTITUTION: A cross inertia moment measuring apparatus for a limit rotating shaft includes a base plate(101). Two first supporting rods(105a,105b) are fixed to the base plate(101) through load cells(103a-103d) so as to support a first rotating axis(120a). A second supporting rod(107) is rotatably installed between the first supporting rods(105a,105b) so as to support a second rotating axis(120b), which is vertically aligned with respect to the first rotating shaft(120a). The second supporting rod(107) has a frame shape. A rotating plate(109) is rotatably installed in the second supporting rod(107). A data processing device(160) is provided to calculate a cross inertia moment.
