Abstract
In a first embodiment of the present invention a method of monitoring individual vibrators in a pneumatic vibration testing system is disclosed. The method includes providing a pneumatic vibration testing system including at least one vibrator, where each vibrator is connected to a pressurized air system through an output of a valve. Pressurized air is then supplied at a known pressure to an input of the valve. When that air is supplied to the valve the valve releases air in measured bursts to the vibrator and the pressure between the valve and the vibrator is monitored. The pressure between the valve and the vibrator is compared to the known pressure, which indicates if the vibrator is failing or has failed. In preferred embodiments, the testing system includes a plurality of vibrators and an equal plurality of valves, each vibrator is connected to the pressurized air system through a single associated valve.
