Condition monitoring of anti-vibration mounts

An apparatus for monitoring an operating condition of an anti-vibration mount, the apparatus comprising:

• a first calculator configured to measure or derive first input data indicative of the amplitude of input vibrations that are applied to the anti-vibration mount;
• a second calculator configured to measure or derive first output data indicative of the amplitude of corresponding output vibrations of the anti-vibration mount;
• and
• a processor unit configured to determine a first set of effectiveness data indicative of the effectiveness of the anti-vibration mount using the first input data and the first output data measured or derived over a first period of time, and to monitor the operating condition of the anti-vibration mount on the basis of the first set of effectiveness data.
