利用模块化的建模方法完成舰船的实体建模,采用有限元软件ANSYS对其进行网格的划分。通过对面元进行热平衡分析,求得舰船红外辐射温度场的分布,建立舰船红外辐射模型,为研究红外导引头识别和跟踪能力奠定基础。同时分析研究了舰船的红外隐身方法,对于舰船的红外隐身设计具有一定的现实意义。
The modeling of the ship was completed by using the modular modeling method. The finite element software ANSYS was used to divide the grid. By analyzing the heat balance of the briquette element, the distribution of the temperature field of the infrared radiation of the ship is obtained, and the infrared radiation model of the ship is established, which lays the foundation for the research on the identification and tracking ability of the infrared seeker. At the same time, the infrared stealth method of the ship is analyzed and studied, which has certain practical significance for the infrared stealth design of the ship.
