The Application of Stewart Platform in Spacesuit Upper Torso Active Fit Design

Abstract

Stewart platform is a typical parallel manipulator, which is equipped with rigidity, high positioning accuracy and other advantages. To achieve wonderful fit of the spacesuit upper torso, the Stewart platform is applied in the upper torso fit design, by which the upper torso active fit design method is proposed. The mathematical model and the experimental model are established to study the validly of the fit design method. The results verify that the application of Stewart platform in the fit design of spacesuit upper torso is feasible. The research in this paper provides useful guide for the fit design of the spacesuit in the future
