For the development of space structures, it is indispensable to evaluate the development characteristics in orbit by a ground test equipment having the function of gravity compensation. However, in the hanging type gravity compensation apparatus mainly used so far, there is an influence of friction of a pulley suspending the structure to be deployed, and the inertial mass due to counterweight and shaking of the wire, to obtain sufficient development evaluation May be difficult. Therefore, we propose a gravity compensator of a new three-dimensional deployed structure and evaluated its feasibility. In this report, we describe the equipment configuration and system requirements, and show the characteristics of gravity compensation from the driving test results using the simple model. As a result, the proposed gravity compensation device has the performance obtained by prediction, and it is expected that it can be applied as a gravity compensation device for three-dimensional deployment structure.
