Abstract
Focusing on the criterion of 'Energy save' or 'Quiet noise' or other suitable operating parameter and considering the existing limitation of the operation of the electro-dynamic shaker system, apparatus for optimizing the operating condition of the vibration test system is proposed. The apparatusmeasures the field current and drive current under the state that the desired vibration is fed to the specimen, and calculates the necessary force the shakershould supply. Field current is supposed to be varied, and the necessary drive current is calculated based on the necessary force data. Further, the blower rotation is supposed to be varied, and the total power consumption at the coils and the blower is calculated. Also the temperatures of the field coiland of the drive coilis estimated and checked whether within the limitation. Then the optimal operating condition for the focused criterion is selected.
