摘要
本文对三级隔振装置进行了研究,该隔振装置是为23kg小型引力波捧状天线而设计制造的。分析表明,该隔振装置的透过率在5000Hz处为10^(-18)量级,满足引力波天线的隔振要求。
A three-stage mechanical vibration isolation apparatus is theoretically andexperimentally investigated. This device is designed and is made for suspendinga 23kg gravitational wave antenna in a cryostat. It is shown that thetransmission ratio of the device is of the order of 10^(18) at 5000Hz which isnear the resonant frequency of the antenna.
