Abstract
Primary angular vibration calibration system and primary angular shock calibration system are developed by Changcheng Institute of Metrology and Measurement (CIMM). The both systems using laser interferometer and grating measure rotational angle, angular velocity and angular acceleration, which are traceable to the International System of Units (SI). This paper will study the dynamic performance of an angular accelerometer and a gyro under the excitation of sinusoidal and shock using the calibration systems. It shows that the angular transducers should be calibrated using both sinusoidal and shock excitation to obtain more detailed dynamic information.
