本文介绍了一种空间六轴隔振器。全文分为三个部分。第一部分回顾了主动隔振的基本原理，总结了基于力反馈的多轴分散控制的主要理论成果。第二部分讨论了技术，并描述了该项目5年来的设计演变。第三部分是传递矩阵的识别和绩效评价。报告了抛物线飞行中的零重力试验。该隔离器在5至400 Hz的频带内被证明是有效的，在50至200 Hz之间的最大衰减为-40 dB。(c)2006爱思唯尔有限公司保留所有权利。
This paper reports on a six-axis vibration isolator for space applications. It is divided into three parts. The first part recalls the principles of active isolation and summarizes the main theoretical results for multiple-axis decentralized control based on force feedback. The second part discusses the technology and describes the evolution of the design over the 5 years of this project. The third part is devoted to the identification of the transmissibility matrix and the performance evaluation. Zero-gravity tests in parabolic flight are reported. The isolator is proved efficient in a frequency band between 5 and 400 Hz, with a maximum attenuation of -40 dB between 50 and 200 Hz. (c) 2006 Elsevier Ltd. All rights reserved.
