Design and analysis of a cable-driven multistage orderly deployable/retractable space telescopic boom
In order to meet the requirement of spacecraft instrument’s repeated deployment, this paper presents a novel cable-driven space telescopic boom (STB) which can be orderly deployable/retractable. First, a novel metamorphic mechanism cell (MMC) which can realize locking, unlocking and interlocking with other cells is proposed, and the metamorphic principle, degree of freedom and motion condition of this type of cells are analyzed. Second, the novel 9-tube cable-driven STB is proposed based on MMCs. Modal analysis of the STB is performed using ANSYS WROKBENCH to verify that the STB has good rigidity. And the kinematics simulation of the STB is conducted using ADAMS software to verify that the deploying and locking functions.
