Study on resonant high-acceleration calibration system

High-acceleration vibrations have a strong effect on parts damage and engine life in the aerospace field. Demand for high-acceleration vibration calibration devices is urgently required. In this paper, a set of resonant high-acceleration calibration system was established. This system generates high-acceleration based on the principle that the resonant beam reaches its natural frequency at the outside frequency to amplify the acceleration amplitude. Experimental results show the system can achieve accurate calibration of sensors at high-acceleration.
