本文介绍了一种用于空间应用的被动六轴隔振系统。该系统由立方体架构的Stewart平台组成；每条腿都配备有连接到 RL 电路的电磁换能器。该系统的行为就像一个弛豫隔离器，其传输率呈现出“40 dB/十年”的渐近衰减率。其性能与基于 skyhook 控制器的有源隔离器非常相似。
This paper describes a passive six-axis vibration isolation system for space applications. The system consists of a Stewart platform with cubic architecture; each leg is equipped with an electromagnetic transducer connected to a RL circuit. The system behaves like a relaxation isolator and its transmissibility exhibits an asymptotic decay rate of ―40 dB/decade. The performances are very similar to that of an active isolator based on a skyhook controller.
