Abstract
CES WORKS is developing a 2-axis joint for small satellite applications. With a range of ration of ±45°, this joint could be used for orienting payloads. This bio-inspired joint is a compliant mechanism, meaning that it is a monolithic system that produces complex movements through the elastic deformation of its structure. Compliant mechanisms do not have backlash or wear which lead to precise motions and absence of lubrication. These qualities are particularly relevant for space applications. A first demonstrator has been 3D printed in Polylactic(Acid) (PLA). The next demonstrator will be made of 3D printed Polyetherketoneketone (PEKK) to determine its compatibility with space environmental conditions. This system is composed of cross-axis pivots that are the focus of this study. To create a numerical twin of the system on ABAQUS© [1], material characterization of 3D printed PEKK is necessary. Printing parameters are known to influence the mechanical properties, especially printing direction [2]. This is why they are also considered in this study.
