[Abstract]:Based on the analysis of the research status of spatial extension arm mechanism at home and abroad, a four-prism shear-fork space extension arm is proposed. On the basis of analyzing the working principle of the extension arm, the configuration characteristics of the folding element (shear element) are determined, and the motion degree of the folding unit is solved based on the spiral theory. The kinematic singleness and folding stability of the four-prism shear-type spatial extension arm are verified. On the basis of this, the geometric characteristics of the folding unit of the spatial extension arm are analyzed, and the diagram of the axial unfolding motion of the folding unit is obtained, and the performance of the extended arm and the accuracy of the repeated deployment are tested in the low gravity simulation environment by using the developed principle device. The results show that the four-prism shear spatial extension arm meets the functional requirements of the space folding mechanism.
