This paper describes the detection of vibration intensity vector using three accelerometers. With this method, the amplitude and direction of vibration intensity vector are obtained by processing three output signals from accelerometers set on beams or plates of a machine structure. Using this method, vibration intensity vectors around the exciting point on a steel plate are measured. The vibration power of bending waves calculated by integrating the vibration intensity vectors is compared with the excitation power measured by an impedance head. The result shows that the three -accelerometer method can be used to detect the vibration intensity vectors. Vibration intensity and reactive intensity vectors on gas heat pump package panels are also measured using this method.
