Relative Technology Research On Vibrator Calibration Accuracy

The theory analysis and experiment research of several technology problems and implements that are relation to improve the accuracy and performace of Vibration Calibration System (VCS) of transducers have been investigated.The dissertation includes six chapters and the contents are as follow:In chapter 1, the characteristic and the signification of vibration transducers are depicted, and the methods and theirs errors of calibration are presented detailed. Then, the general situation of the development of VCS in domestic and abroad is introduced. The important signification of improving the performances of VCS is expounded. Finally, the intention and the task of this paper are put forward.In chapter 2, based on the analysis of calibrating vibrator's principle, we research the characteristic of frequency response, resonance of vibrator's moving parts and cross movement of working table. Some theories about how to output high quality acceleration waveshape from working table present in this chapter.
