本文的目的是审查和讨论的主要问题发生在主加速度计校准由于使用不完善的激振器。这些问题包括低运动元件刚度、校准下的加速度计发热、摇摆和横向运动、共振、谐波失真和噪声。采取的方法，以尽量减少这些问题的影响进行了讨论，并在此提出了一些校准结果。(C)2009爱思唯尔有限公司保留所有权利。
The purpose of this paper is to review and discuss the main problems that occur in primary accelerometer calibration due to the use of imperfect vibration exciters. These problems include low moving element stiffness, heating of the accelerometer under calibration, rocking and transverse motion, resonances, harmonic distortion and noise. Methods undertaken to minimize the effects of such problems are discussed and some calibration results are presented herein. (C) 2009 Elsevier Ltd. All rights reserved.
