摘要：

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.
