Corrosion Analysis of Radar Typical Component Based on High Humidity and High Salinity Environment
This paper studies the mechanism of the corrosion of typical radar component working for the longterm in the environment of high temperature, high humidity and high salt fog. It puts forward the simulation calculation method of radar typical components in the environment, establishes the finite element model of radar typical components and conducts simulation analysis with computational fluid dynamics (CFD) software FLUENT for platform. The distributions of temperature, humidity and salinity of typical radar components are obtained. The simulation result shows the corrosion degree of parts surface is above 0.6mm and serious, which is in agreement with the actual radar equipment test result. In addition, from distributions of the simulation, the single temperature or salinity has little influence on the corrosion of the surface of the parts, while the humidity has a significant impact on the corrosion. It proves the rationality and correctness of the simulation calculation method, and provides a theoretical guidance for the further study and prevention of radar equipment corrosion of the typical parts of the radar.
