前言由于近几年来形形色色结构与机器设计的进展,相应出现了更多的振动问题。精确测量冲击与振动的必要性变得十分重要。因此,为优选振动传感器的结构与规定其校准方法付出了很大的努力。本文着重论述压电加速度计的动态校准方法。压电加速度计已很普及,因为它对质量比的灵敏度高而对不利环境的灵敏度低。压电加速计的频率范围与动态范围很宽,适合于当前先进的测量与分析设备的性能。校准一般是指用于检验可能影响传感器测量精度的全部工作特性的过程。即使时间和外 Foreword Due to the progress of all kinds of structures and machine designs in recent years, more vibration problems have appeared correspondingly. The need to accurately measure shock and vibration becomes important. Therefore, great efforts have been made to optimize the structure of the vibration sensor and specify its calibration method. This article focuses on the piezoelectric accelerometer dynamic calibration method. Piezoelectric accelerometers have become popular because of their high sensitivity to mass ratio and low sensitivity to adverse environments. Piezoelectric accelerometers have a wide frequency range and a wide dynamic range, making them suitable for the performance of today’s advanced measurement and analysis equipment. Calibration generally refers to the process used to test all operating characteristics that may affect the accuracy of a sensor’s measurement. Even time and time
