Study of Dynamics Simulation on Large Space Deployable Membrane Structures
摘要
Abstract
Space-based Synthetic Aperture Radar (SAR) antenna is focused on high-resolution earth-observing field widely for its special applied purpose.Due to the characteristics of light-weight,large-size and various frame,the large space membrane structure is used for SAR antenna.In order to know its on-orbit dynamics performance,the dynamics model is built,based on the method of temperature-structure pre-stress introduction.Design parameters such as material performance,membrane thickness,and pre-stress etc.are analyzed on how to affect the SAR antenna dynamic performance.The results indicate that the pre-stress of membrane is the key factor for the whole structure mode index,and the other parameters have less effect and can be ignored.Dynamics performance of the parameters is analyzed,and optimization design is discussed,and main design parameters are obtained through the dynamics model.Research results can provide reference and guidance for the engineering design of the large space membrane structure.关键词
