采用数值模拟方法对风一车一桥耦合系统的车桥气动特性进行分析研究，模拟计算了不同工况下车 辆、桥梁的气动力系数．分析了车桥问相互的气动影响，研究结果表明．车桥耦合系统与桥梁和车辆各自单体 相比较．气动力系数差异较大．故建议进行风一车一桥系统耦合振动分析时。车桥气动力系数应考虑车桥问 的气动影响．(The numerical simulation method axle aerodynamic characteristics of the the wind car bridge coupling system analysis, simulation under different conditions of vehicles, bridges aerodynamic coefficients. Analysis of the influence of the mutual pneumatic axle Q, the study results show that. The axle coupling system with the respective bridges and vehicles monomer comparison. Aerodynamic coefficients quite different. It is suggested that wind car bridge system coupled vibration analysis. Axle aerodynamic coefficients should consider impact of axle ask pneumatic.)

数学建模,很简单的，希望对你们用帮助，望下载！(Mathematical Modeling)
