| Abstract: |
| Objective To study the influence mechanism of corrosion typical radar component working for a long-term in environment of high temperature, high humidity and high salt fog. Methods A simulation calculation method of radar typical components in the environment was proposed. A finite element model of radar typical components was established with the computational fluid dynamics (CFD) software FLUENT as platform to conduct simulation analysis. Results The distributions of temperature, humidity and salinity as well as comprehensive environment corrosion of typical radar components were obtained. The corrosion degree of parts surface was above 0.6mm and serious, which was in agreement with the actual radar equipment test result. In addition, from distributions of the simulation, the single temperature or salinity had little influence on surface corrosion of parts, while the humidity had a significant impact on the corrosion. Conclusion It proves the rationality and correctness of the simulation calculation method, and provides a theoretical guidance for further study and prevention of radar equipment corrosion of typical radar parts. |
