| Abstract: | The space inflatable structure mainly made of membrane materials is a new type of structure.It can be used as large antenna,solar concentrator,solar sail and other space structures and offers an effective approach for large space structures.Dynamic characteristics are essential problems in design process of inflatable structures,while dynamic analysis and test are always the key problems in the research of inflatable structures. Because of special features of inflatable structures in materials,structural style and working environments,there are many new problems in dynamic analysis and test.The dynamic analysis of space inflatable structures at present includes experimental research and numerical simulation.In the experimental research,contact testing mediums are being replaced by contactless methods to obtain the characteristics of the inflatable membrane structures,but it faces serious problems in conditions of vacuum and micro-gravity.The numerical methods can effectively simulate the dynamic behaviours of structures in conditions of vacuum and micro-gravity and analyse the coupling effects of gravity,air and winkles on the structural vibration characteristics.This paper reviews the development and the present state of experimental and numerical researches on vibration analysis of space inflatable structure and discusses the existing problems,and gives the trend of development. |
