    The environment in space provides favorable conditions for space missions. However, low frequency vibration poses a great challenge to high sensitivity equipment, resulting in performance degradation of sensitive systems. Due to the ever-increasing requirements to protect sensitive payloads, there is a pressing need for micro-vibration suppression. This paper deals with the modeling and Author: Qianqian Wu, Ning Cui, Sifang Zhao, Hongbo Zhang, Bilong Liu.

    Vibration Isolation. Vibration isolation often is assumed to be a component property, i.e. something exclusively related to the isolating spring component or the resonance frequency of the mass-spring system (see Figure 1).. The component property assumption is of importance as it affects how we act and think when dealing with vibration isolation. The purpose of vibration isolators is to seperate or isolate an.

    NASA/JPL needed a dynamic test bed for the Space Interferometry Mission (SIM) to demonstrate spacecraft vibration-induced errors of a few nanometers. They selected a Minus K Hz vibration isolation system for Zero-G simulation and to mitigate floorinduced vibrations into the System Test Bed 3 (STB3), which helped to achieve this important goal.

NONINTRUSIVE INERTIAL VIBRATION ISOLATION TECHNOLOGY FOR MICROGRAVITY SPACE EXPERIMENTS Carlos M. Grodsinsky and Gerald V. Brown National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio Abstract The dynamic acceleratlon enviror_ment observed on Space Shuttle flights to date and predicted for.

The dynamic acceleration environment observed on Space Shuttle flights to date and predicted for the Space Station has complicated the analysis of prior microgravity experiments and prompted concern for the viability of proposed space experiments requiring long-term, microgravity environments.

Isolation systems capable of providing significant improvements to this environment exist, but at. Nonintrusive inertial vibration isolation technology for microgravity space experiments. Active control of vibration isolation with discrete frequency agitation for space experiments. 17 August Acceleration levels and operation of the Microgravity Vibration Isolation Mount (MIM) on the shuttle and the Mir space station.

The International Space Station (ISS) is being envisioned as a laboratory for experiments in numerous microgravity (μg) science disciplines. Predictions of the ISS acceleration environment indicate that the ambient acceleration levels will exceed levels that can be tolerated by the science experiments.

[Carlos M Grodsinsky; Gerald V Brown; Lewis Research Center.]. Interest in vibration isolation for microgravity experiments has increased within the microgravity sci- ence community as the flight program has progressed and the small, but significant levels of residual accelera- tion on the Space Shuttle (STS) have become more widely recognized and documented (Hamacher, WorkshopCited by: Many microgravity space-science experiments require active vibration isolation, to attain suitably low levels of background acceleration for useful experimental results.
