| Abstract: | The space deployable hexapod parabdoid truss antenna presented in this paper is based on the hexahedron module can stow and deploy with the stretching and shortening of the diagonal members. The deployable power is provided by the tension spring in the diagonal rod, and there is no need for extra force. Various deployable structures can be formed by connecting more than one hexahedral module together. A most important feature is that there is no mechanism to be locked when the structure is deployed. Its packaging efficiency and stiffness have been shown to be good too. This antenna is designed by using a deployable hexapod truss has light mass and high precision. Structure analysis revealed the high of rigidity the antenna. |
