Abstract: The development status and characteristics of the mechanical design of deployable membrane sunshields for spacecraft are reviewed from aspects of its geometric configurations, deployment driving method, membrane folding pattern design and simulation methods of membrane with wrinkles. On the basis of the analysis and comparison, the development trend of the mechanical design of deployable membrane sunshields is proposed, aiming at inspiring the future design of this component.
