摘要
建立了桥梁三维瞬态温度场及整体辐射通量计算模型 ,较全面地考虑了太阳、大气、河流、车辆等因素对桥梁温度分布的影响 ,并以当前广泛采用的混凝土箱型梁桥为例 ,用有限差分的方法对桥梁进行了红外热像数值模拟。
The model for calculation of the 3D transient temperature and irradiative flux of a bridge, with comprehensive consideration of the influence of sun, air, river, vehicle and so on, has been developed. Simulation of the infrared signatures of a bridge is also carried out using the finite difference method for the widely used concrete box girder bridge.
