Design and Deploying Characteristics Analysis on Two-stage Helical Repeated Fold-unfold and Lock-unlock Solar Wing

Two-stage helical repeated fold-unfold and lock-unlock solar wing is designed.Its function analysis is conducted.Firstly,its working principle is analyzed.Based on the requirement of two-stage helical repeated fold-unfold and lock-unlock solar wing,technological parameters and specific structural parameters are determined.The fold-unfold and lock-unlock solar wing unfolding characteristic is analyzed.According to the transitive relation analysis of repeated fold-unfold and lock-unlock solar wing,the analysis modeling on its deploying kinetic characteristics,including forward kinematics and inverse kinematics,are derived.Simulation results show that plane degree and synchronization degree of the solar wing can meet the requirements of specifications,which lays the theoretical foundation to further research the fold-unfold and lock-unlock solar wing in the future.
