Abstract

The space inflatable structures have received increasing attention in recent years. Inflatable boom is the fundamental structural part to help space inflatable structures maintain the expected configuration. In this paper, the methodology to control local wrinkle growth and the deformation configuration of the inflatable boom structure with Shape Memory Alloy (SMA) wires actuator is developed. The experimental equipment has been established to investigate the growth of wrinkling and the control abilities of SMA actuator, wavelength and amplitude parameters of the wrinkling deformation have been measured by non-contact deformation test system. To understand the behavior of an inflatable boom due to wrinkling, the boom structure is numerically modeled using the ANSYS FE program with the equivalent nodal force method. The recovery force generated by the SMA wires could remove wrinkling and restore the deformation of the inflatable boom. The results from the experiment and numerical analysis show that SMA wires can eliminate the wrinkling deformation of inflatable boom effectively.
