- Abstract:
- Vibration exciters can cause several problems of vibration calibration. The classical one comes from the exciter resonances, which are closed to some calibration frequencies. Although efforts have been made in the design stage to overcome the resonance problems, some of them still exist in particular calibration conditions. In this paper, the resonances of a Brüel & Kjær vibration exciter system (model 4805 with 4811) are studied theoretically and experimentally. A mass-spring model is used to describe the vibration characteristics of the exciter system. The measured resonances are extracted from the measured frequency response of the system. The influence of exciter resonance on the primary calibration of accelerometer is preliminarily investigated.
