摘要

在此基础上，提出了适用于压电加速度计工作原理的数学模型，并通过仿真验证了该模型根据频率比和阻尼率将精度与测量误差联系起来。该模型的建立为提高加速度计的精度、灵敏度和可靠性等性能提供了可能，并提出了加速度计的新概念。结果表明，阻尼比的选择对加速度计参数的发展和振动分析技术的提高具有重要意义。

Improvement of the Vibratory Analysis by Enhancement of Accelerometer Characteristics

In this work, the mathematical model suitable for the operating principle of the piezoelectric accelerometer is extracted then this model which connects the accuracy and the measurement error according of the frequency ration and the damping rate is validated by simulation. The model developed makes it possible to improve the performances of the accelerometer such as precision, sensitivity and reliability as well as to propose a new conception of the latter. A comparative study is made to show the importance of our results compared to literature, these results have showed that a suitable and appropriate choice of damping ratio develops the accelerometer parameters and enhances the vibratory analysis technique.
