Simulation and testing analysis of the vibration characteristics of the panoramic sight platform during the driving of a certain tank
View through CrossRef
Abstract
To study the vibration characteristics of the panoramic sight platform during the driving of a certain tank, the vibration transmission path of the tank was analyzed, modal simulations were performed on the turret, the carrier platform of the panoramic sight platform, the vibration characteristics of the panoramic sight platform during the driving of tank under different working conditions were tested. The results showed that the vibration modes of the turret were located at the location of panoramic sight platform in the third, sixth, and eighth modes, with natural frequencies of 52.439 Hz, 65.012 Hz, and 87.064 Hz, the main response frequency of each structural component of the panoramic sight platform ranged from 46.5 Hz to 52.5 Hz, which was consistent with the main excitation frequency of the turret and the simulated natural frequency. Therefore, resonance was prone to occur in the panoramic sight platform. The simulation and test results have certain engineering guidance significance for the design and overall layout research of tank panoramic sight platform.
