“…12 The full model for the deployment of an equal sense, two-dimensional tape-spring fold is based on the modeled moment rotation plot shown in Fig. 13, where the coordinates of the critical points can be calculated from both analytical expres- sions (derived by Wüst 13 and Rimrott 14 ) and polynomial functions (derived by Seffen et al 12 ) within reasonable accuracy limits. In this current work the tape is modeled as a simple hinge in order to study the impact of the steady-state moment rise on the system dynamics, as this is the largest time segment of the tape-spring deployment [especially if θ(at t = 0) = 180 deg].…”

One of the most significant drivers in satellite design is the minimization of mass to reduce the large costs involved in the launch. With technological advances across many fields, it is now widely known that very low-mass satellites can perform a wide variety of missions. However, the satellite power requirement does not reduce linearly with mass, creating the need for efficient and reliable small satellite deployable structures. One possible structural solution for this application is tape springs. Tape springs have been previously studied in many countries for space applications focusing on two-dimensional systems. This work studies the possible impact of using tape springs folded in three dimensions. By first analytically determining the static moments created, simple deployment models can be constructed for tape springs in free space. Then, determining the impact of these moments about an array fold line allows the creation of a dynamic model of an array that is directly comparable to the two-dimensional system. The impact of the three-dimensional fold can then be determined.

“…The fully open expandohedron has a number of mechanisms, see below, but the addition of e.g. locking hinges (Seffen et al, 1999) would give rigidity to the deployed structure. This paper has therefore two aims.…”
