| Abstract: | A motor-isolator-seating arrangement is set up and predictions of the vibration transmission to the seating via the isolators is made by using the frequency averaged frequency response characteristics of the seating and motor. These estimates are compared with power measurements made by using alternative methods incorporating frequency response data and accelerations at connecting points. In general, the measurements are found to be in agreement with the predictions, with the exception occurring when significant airborne noise excited the seating. The effects of multipoint couplig are discussed. |
