Abstract
Light-weight origami-inspired mechanisms can provide advantages in deployable space systems and other applications. However, a significant challenge in their design is ensuring that they are sufficiently stiff. Compliant, deployable stiffeners utilizing a profile approximating the Euler Spiral are proposed as one solution. Structures with this profile, called a lenticular stiffener, are shown to permit stiffeners to flatten using forces applied at their edges. Formulas for calculating the stiffness increase are developed. Relations needed to design the deployment behavior of the stiffeners are also derived. Finally, advantages of different stiffener configurations are evaluated. These results are verified through simulation and experiments.
