A simulation test equipment of biaxial low frequency angle disturbance

Gyro stabilized platform is sensitive to external angle change, and is mainly used to effectively isolate the influence of angle disturbance on the attitude maintenance of stabilized platform([1-3]). In order to provide the simulation environment of external angle disturbance for the stable platform([4]), this paper designs an azimuth and pitch two-dimensional angular motion excitation device, which can effectively simulate the low-frequency angular disturbance condition below 20Hz. The angular motion range can reach +/- 50 degrees azimuth, and the pitch axis can reach +/- 70 degrees . The positioning accuracy is 10 ''. The device provides a good man-machine interface, which can display the motion data of each axis in real time. At the same time, considering the safety of use, the design has electrical, software and mechanical multi-level limit measures, which can realize automatic monitoring and system protection.
