Vibration simulation analysis of shipborne communication terminal receivers

Alongside the swift progression of modern maritime technology, the stability and reliability of shipborne communication terminal receivers have become increasingly crucial for the normal operation of ships. This study revolves around shipborne communication terminal receivers, capitalizing on finite element tools to analyze the first six natural vibration frequencies of the receiver, namely 94.596Hz, 141.84Hz, 147.01Hz, 158.65Hz, 179.67Hz, and 222.17Hz. Additionally, the impact of external excitations during practical usage on the internal core components of the device is examined. The findings reveal that under the operational state of the internal chips within the receiver, the maximum velocity along the X-axis response spectrum is 4.424mm/s, representing a 26.27% reduction compared to the ship's inherent vibrations. Furthermore, the maximum velocity along the Z-axis response spectrum for the chips is 4.539mm/s, indicating a 24.35% decline compared to the ship's vibrations. This research aims to provide insights and establish a scientific theoretical foundation for the structural design and optimization of shipborne communication terminal receivers.
