Abstract:

This report provides a summary of the motivation, methodology and research results for two different projects supported under this effort. In Electrically integrated active compliant transmission ACT Actuation Technologies two different actuation approaches were developed, modeled, fabricated and experimentally validated 1 a d31-approach based on the Recurve architecture that generates higher forces and 2 a d33-approach based upon a compliant mechanism that provides more amplified strain. A first-generation power amplifier was designed that efficiently swaps energy allowing low voltage batteries to produce high voltage drive signals. Both piezoceramic actuation systems were integrated into the INertially STAbilized Rifle INSTAR to eliminate aiming errors by stabilizing the barrel assembly providing a significant advancement in small arms. In the second project, Proof-of-Concept Investigation of Active Velcro Autonomous Docking of Micro- and Nano-Satellites, a new connection methodology, Smart Attachment Mechanism SAM technology, was invented, modeled and experimentally characterized that possesses the ability to actively connect two surfaces engagement, retention, release and effect relative planar motion between them translation, rotation. This work laid the necessary foundation for further development of this unique paradigm which is useful for any unstable environment space, fluidic, moving, vibration, etc where active connection and motion is simultaneously required.
