Abstract
An apparatus for measuring vibration of a fan includes a frame having an opening for enclosing a fan; a plurality of accelerometers disposed on the frame; and an elastic support for supporting the frame. An apparatus for measuring fan vibration includes a frame having an opening for enclosing a fan; a plurality of accelerometers disposed on the frame. The plurality of accelerometers output a signal to the signal-analyzing device and at least three of the plurality of accelerometers are disposed on a different surface of the frame from each other. The apparatus for measuring fan vibration includes a mounting block that allows the fan to be secured in the opening of the frame and an elastic support for supporting the frame. A method of measuring fan vibration includes disposing a plurality of accelerometers on a frame; mounting a fan within the frame; turning on the fan; and outputting a signal from each of the plurality of accelerometers to a signal-analyzing device.
