摘要：这份报告总结了这项工作支持的两个不同项目的动机、方法和研究结果。在电集成主动柔性传动(ACT)驱动技术中，开发了两种不同的驱动方法，并对其进行了建模、制造和实验验证：1)基于递归结构的D31方法，可产生更高的力；2)D33-方法，基于提供更大应变的柔顺机构。设计了一种第一代功率放大器，可以有效地交换能量，使低压电池产生高压驱动信号。这两种压电陶瓷驱动系统都被集成到惯性稳定步枪(INSTAR)中，通过稳定枪管组件来消除瞄准误差，从而在小型武器中实现了重大进步。在第二个项目-微纳卫星主动维可牢自主对接的概念验证研究中，发明了一种新的连接方法-智能附着机构(SAM)技术，并对其进行了建模和实验表征，该技术具有主动连接两个表面(接合、保持、释放)和影响两个表面之间的相对平面运动(平移、旋转)的能力。这项工作为进一步发展这一独特的范式奠定了必要的基础，这种范式对任何需要同时进行主动连接和运动的不稳定环境(空间、流体、运动、振动等)都很有用。
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.
