微小重力下における組立作業特性に関する研究

抄録

In this paper we measure assembly characteristics in pseudo-microgravity space for the purpose of facilitating design of equipments that enable a Person to carry out assembly tasks precisely and quickly in outer space. First, we design a working bench which has 3 degrees of freedom and creates a pseudo-microgravity state record for the experiment. With the device we measure how much force is used and analyze how the human body moves in basic motions, such as "turn", "pull" and "push". Next, we apply the above method to assembly tasks. We clarify how three factors (work attitude, kind of tools, and position for supporting the body) affect the force used and how they change the attitudes of the body and an object.
