“…Sodano et al [7] used multiple MFC devices for vibration control of inflatable torus. Meanwhile, Sakamoto et al [8] controlled wrinkling of flat membrane by tensioning the distributed cable activated using MFC as an out-of-plane actuator in finite element analysis, and Tung et al [9] designed and fabricated a MEMS-based flexible sensor and actuator system to monitor and control the health of inflatable space structures. Because the SMA wire actuator has the same advantages of the smart film such as flexibility and adaptability to arbitrary shape, the smart wire is also effective to control shape and deformation of inflatable structures.…”

The methodology to restrain the growth of wrinkling region in inflatable boom is numerically and experimentally investigated. The inflatable boom structure is numerically modeled by using ABAQUS finite element program with membrane elements. To consider the nonlinear deformations of inflatable boom due to wrinkling, the numerical algorithm of wrinkling based on Miller-Hedgepeth membrane theory is developed using user defined material (UMAT) subroutine supported by ABAQUS. The experimental model of inflatable boom is made of Kapton film. To characterize the nonlinear behaviors of inflatable boom, the bending tests for various internal pressures are performed. To delay the growth of wrinkled region and restore the deformed shape of inflatable boom, shape memory alloy (SMA) wire actuator attached on surface of the structure is applied.

“…In order to maintain the flexibility of the membrane, film and wire type smart materials are preferred such as macrofiber composites (MFC), shape memory alloy (SMA) films or wires, and electroactive polymers (EAP). Sodano et al [6] used multiple MFC devices for vibration control of an inflatable torus, and Sakamoto et al [7] controlled wrinkling of a flat membrane by tensioning the distributed active cables using MFC as an out-of-plane actuator in finite element analysis. For the application of a SMA strip actuator to shape-adaptive structures, the thermomechanical responses of SMA and the interactions between the host structure and the actuator are numerically investigated by considering the 3D effect of SMAs [8].…”

Inflatable boom is a fundamental structural part of inflatable space structures maintaining the expected configuration of the whole system, supporting external loads and guaranteeing the efficiency of the membrane surface. The inflatable structure is a thin film structure compactly packaged and expanded to the desired configuration by the internal gas pressure. But, the structures can be easily distorted and even collapsed by wrinkling. In this study, the behavior of an inflatable boom structure is investigated numerically and experimentally. To achieve a better bending strength, the methodology to control the wrinkling growth and the deformed configuration of the inflatable boom structure with shape memory alloy (SMA) wire actuator is developed. For understanding of the nonlinear behaviors of an inflatable boom due to wrinkling, the structure is numerically modeled using ABAQUS finite element program with wrinkling algorithm developed based on the Miller-Hedgepeth membrane theory. To verify the present analysis method, the inflatable boom made of Kapton film is examined by the bending tests with various internal pressures. To delay the growth of wrinkling that rapidly deteriorates the bending strength of the inflatable boom, SMA wire actuator is applied. SMA wires are attached on the edge of inflatable boom and generate recovery force to remove wrinkling and restore the deformation of the boom.
