Vibration reduction technology of airborne photoelectric stabilized sighting platform

The vibration of the equipment ring frame will be caused by the interfence factors of aircraft combat environment of airborne photoelectric stabilized sighting platform, which has a great influence on the stability and tracking accuracy of load optical axis of photoelectric platform. The main task of vibration reduction is to effectively isolate the ambient vibration. Compared with the traditional rubber shock absorber, a new flexible vibration reduction design of airborne photoelectric stabilized sighting platform was proposed. The modal simulation analysis of the new vibration reduction model was carried out by ANSYS simulation software. Finally, the performance of the design was evaluated effectively by vibration test. The error between the test results and the simulation evaluation is 0.56%, which shows that the design has the ability of vibration reduction to airborne photoelectric stabilized sighting platform.
