Design and analysis of a sleeve type spiral deployment coilable mast

This study suggests the development program of a sleeve type spiral deployment coiled mast using the combination of threaded cylinder and straight guide cylinder, with the goal of designing the sleeve type spiral deployment coiled mast and addressing the crucial issue of whether the mast can be smoothly retracted. In order to predict the overall performance of the ground prototype, this paper adopts the virtual prototype technology, based on ADAMS software, establishes the dynamic simulation model of the sleeve type spiral deployment coiled mast, simulates the retraction and extension process of the mast, and analyzes the deformation characteristics of the crossbar in the transition zone in the post-flexion state. Finally, the ground test of the mast retraction and extension was carried out by the assembled ground prototype. The destabilizing deformation of the triangular cross frame during the mast's deformation process was used to determine the working principle of the mast using elemental instability. The simulation results were compared with the experimentally obtained relationship curves between the change in the mast's length with the chassis angle during the retraction and extension process and the change in the mast's coiled radius in the transition zone, confirming that the simulation model was in the post-flexion state. Comparison is made with the simulation results to verify the correctness of the simulation model and the feasibility of the design scheme.
