Title:
GROUND TESTING DEVICE FOR SPACE DEVICE
Document Type and Number:
Japanese Patent JPH01182200
Kind Code:
A
Abstract:
PURPOSE:To enable execution of further accurate compensation for gravity without exercising an influence on a development motion, by a method wherein based on detection of component of force of tension, a suspension thread is moved so that it extends vertical to a development direction. CONSTITUTION:With a motor 5 for development run, an antenna pedal 3 starts a development motion, a wire 25 coupled to the rotating end of the pedal 3 is displaced by a given angle from a vertical direction, and fine strain is produced at thin section parts 21 and 22 through a wire support piece 19 by means of a shearing force. First-fourth strain gauges 33, 35, 37, and 39 detect fine strain of the thin section parts 21 and 22, and through running of a motor 17 according to a strain amount and a strain direction, a carrier 13 is moved in the strain direction of the thin section parts 21 and 22 according to a strain amount. Thus, the carrier 13 can be moved following the development motion of the pedal 3 so that the wire 25 extends vertically to the development direction. This constitution enables further accurate compensation of the pedal 3 for gravity by means of a counter weight 31.
