Study on Dynamic Characteristics of Photoelectric Platform of A Tracked Anti-aircraft Gun

Aiming at the issue that the photoelectric platform’s imaging quality and tracking accuracy are affected by the vibration impact of the artillery launch, based on the structural characteristic and constraints of a tracked anti-aircraft gun, considering the elastic deformation factors of the platform, bracket and bearing, etc. The rigid-flexible coupled launch dynamic model of the gun is used to study the vibration response characteristics of the photoelectric platform under three typical operation conditions. The impact vibration test of the platform mount under typical shooting conditions is carried out. The vibration response data is analyzed by the power spectral density function, and the dynamic response features of the photoelectric platform are obtained. The theoretical calculation results are consistent with the experimental test results, which provides a reference for the optimization design of the photoelectric platform on tracked anti-aircraft gun.
