Device and method for calibrating amplitude consistency in frequency domain of acceleration sensor

The invention discloses an amplitude consistency calibrating device and method in an acceleration sensor frequency domain, and belongs to the technical field of automobile NVH vibration test evaluation, and the device comprises an acceleration sensor, a workbench, a connecting line, a data control acquisition system, an air spring, a base and a vibration exciter. A data analysis specific frequency range is carried out; a reference evaluation acceleration sensor is determined; an arithmetic root-mean-square method is used to calculate the acceleration of other acceleration sensors in different frequency ranges; and if the acceleration is smaller than a certain value, it is determined that the frequency domain amplitude of the acceleration sensor meets the requirement. According to the method, the amplitude consistency of the acceleration sensor is verified and evaluated, the accuracy of test data of the acceleration sensor in a frequency domain is objectively reflected, and accurate vibration data support is p
