Paper Abstract

This paper describes the status of on-going work at the vibration and shape control of large inflatable deployment structures. It presents a brief summary of the related concepts in inflatable deployment structures, smart structures and the applications between them. Inflatable deployment structures which made of thin membrane can hardly achieve high surface precision and good dynamic properties. Smart materials and structures can be used to adjust boundary and membrane surface, which give the ability of vibration and shape control. Results indicated that the use of smart materials and structures might easily help inflatable deployment structures reduce vibration and achieve higher surface precision. A large-scale and light weight reflector model mixed with inflatable deployment and rib-support structure was developed. It is constructed by five parts: central connection tank, radial supporting ribs, inflation bags, meshed reflective surface and supporting booms. To improve surface precision, some sensors and actuators made of smart materials could be designed to guarantee the reflector model has more control authority over the whole structure.
