对桥梁结构进行分析及简化，提出了基于OpenFlight模型的通用桥梁建模方法，将梁式桥、斜拉索桥、拱桥和悬索桥统一为一种通用的模型结构，并分别针对桥梁箱体结构、主缆、索塔、护栏等典型部件的热特性，综合考虑各种自然因素，建立桥梁红外辐射特性计算理论模型，并以图像的灰度信息模拟红外辐射特性，开发了通用的桥梁红外辐射特性计算及成像仿真软件系统，实现了任意时刻、任意地理位置、任意气象条件下不同类型桥梁的红外辐射特性模拟。实验结果表明提出方法与现有桥梁红外成像仿真结果具有一致性，符合典型桥梁的红外热辐射规律。

A new general modeling method for bridge based on the OpenFlight model is proposed by analyzing and simplifying the structure of bridge, making the girder-type bridge, suspension bridge, arch bridge and cable bridge a general model structure. Aiming at heat characteristics of box girder, cable, railing and other typical part of bridge, the computational model for infrared radiation characteristics is built by considering a variety of natural factors, which can be simulated through image gray information. Moreover, a general software system is developed. Experimental results show that the method can effectively simulate the infrared radiation characteristics of bridge at any time, any geographical position and any meteorological environment.
