Abstract

This paper focuses on marine large display terminals and systematically investigates their vibration response characteristics using the finite element analysis method. First, through modal analysis technology, we extracted the first six natural frequencies of the display terminal: 86.47 Hz, 87.42 Hz, 100.68 Hz, 215.66 Hz, 253.73 Hz, and 292.94 Hz. These natural frequencies reveal their dynamic characteristics under free vibration states. Second, we analyzed the deformation and stress distribution of the display terminal under static loads. Results show a maximum vertical deformation of 0.034 mm and a maximum equivalent stress of 19.284 MPa, verifying structural stability under static conditions. Additionally, random vibration analysis was employed to evaluate the terminal’s response under dynamic loads. The analysis revealed a maximum random vibration displacement of 13.8353 mm (99.73% confidence interval) at the damping device and 4.3471 mm (99.73% confidence interval) at the centroid, confirming the effectiveness of the damping system. Finally, to simulate the vibration behavior of terminals in real navigation environments, we specifically considered the impact of external excitation under extreme weather conditions. Results indicate that the terminal’s maximum resonant frequency is approximately 88 Hz, with the largest external excitation displacement below 0.1 mm, demonstrating robust stability in complex vibration environments.
