CONDITION MONITORING OF ANTI-VIBRATION MOUNTS

摘要

Monitoring the condition of an anti-vibration mount, e.g. a sandwich mount in which a plurality of elastomeric layers are interleaved with rigid plates. A set of effectiveness data is determined using input and output data measured or derived over a period of time. The effectiveness data is indicative of the effectiveness of the anti-vibration mount, in particular is dynamic stiffness. The input data is indicative of the amplitude of input vibrations that are applied to the anti-vibration mount and the output data is indicative of the amplitude of corresponding output vibrations of the anti-vibration mount (e.g. the vibrations that are transferred into an external support frame of the associated apparatus or equipment). The operating condition of the anti-vibration mount is monitored using the set of effectiveness data, e.g. by comparing successive sets of effectiveness data determined using input and output data collected over different time periods.

1. A method of monitoring an operating condition of an anti-vibration mount, the method comprising:
determining a first set of effectiveness data indicative of the effectiveness of the anti-vibration mount by:
measuring or deriving first input data indicative of the amplitude of input vibrations that are applied to the anti-vibration mount and first output data indicative of the amplitude of corresponding output vibrations of the anti-vibration mount, the first input data and the first output data being measured over a first period of time; andusing the input data and the output data to determine the first set of effectiveness data; and monitoring the operating condition of the anti-vibration mount on the basis of the first set of effectiveness data.
