摘　　要：针对旋转角加速度传感器标定困难这一问题,提出了一种能够校准旋转角加速度传感器的方法。角加速度激励源采用伺服电动机产生,被校准的传感器与激励源同轴连接,通过调节激励源的电参数,能够产生幅值可调的旋转角加速度量值,测取角加速度传感器的输出电压值后即可实现标定。本文详细阐述了激励源的角加速度产生机理,推导了角加速度量值的理论公式,给出了计算角加速度量值所需参数的测取方法,最后对感应式角加速度传感器进行了校准实验,验证了标定方法的可行性。For the calibration problem of angular acceleration sensor,a calibration method is presented in this paper.The angular acceleration excitation source is generated by servo motor,and angular acceleration sensor is connectedwith the excitation source coaxially. The amplitude of angular acceleration can be adjusted by adjusting electrical pa-rameters of excitation source,the characteristic of sensor is received after measuring the sensor output voltage. Inthis paper,the working mechanism of angular acceleration excitation source is described in detail,the theoretical for-mula of angular acceleration is deduced,and the parameters measuring method for calculating angular accelerationis given. Finally,a induction angular acceleration sensor is calibrated by this method,and the feasibility is verified.
