High frequency data processing method of the force balance vibrating accelerometer

Abstract

This paper studies the force-balance transducer digital recording of the offshore platform vibration detecting comprising instrumental high-frequency error correction data processing question primarily. The paper elaborated the data processing algorithm and introduced in detail the error correction of the instrument with the method of successive acceleration formula. To exemplify this theory, this article has given the newest adjustment processing result of the largest number character style record obtained in the May 12, 2008 Wenchuan earthquake. Furthermore, it also has provided macroseismic recording correction results of the offshore platform vibration examination with the wireless force-balance Vibration Sensor. The results indicate that the newly-proposed method of the data processing containing the instrumental high-frequency error correction of the force-balance sensor digital recording will obtain "the high fidelity" test data, which is more suitable for the application of structural parameter identification.
