中文摘要:
      目的 研究雷达典型部件长期工作在高温、高湿、高盐雾等环境下腐蚀情况的影响机理。方法 提出在该环境下对雷达典型部件多场耦合的仿真计算方法,以计算流体动力学(CFD)软件FLUENT为平台,建立雷达典型部件的有限元模型,对雷达典型部件进行仿真模拟分析。结果 得到了雷达典型部件的温度、湿度和盐度分布云图和综合环境腐蚀云图,从腐蚀云图可以看出,部件表面腐蚀程度在0.6 mm以上,腐蚀程度比较严重,仿真结果与实际检测结果较为吻合。从分布云图可知,单一的温度或盐度因素对部件表面的腐蚀情况影响较小,湿度对其影响较为显著。结论 验证了仿真计算方法的合理性和正确性,为雷达典型部件的动力学仿真,为其腐蚀现象的进一步研究及预防提供了理论指导。
英文摘要:
      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.
