将列车桥梁系统视为一整体.根据随机振动能量理论,以列车构架人工蛇行波和实测蛇行波为横向激振源,计算了准高速列车以不同的速度通过钢筋混凝土连续梁桥的振动反应.与测试结果比较,本文的计算结果是比较满意的.
將列車橋樑繫統視為一整體.根據隨機振動能量理論,以列車構架人工蛇行波和實測蛇行波為橫嚮激振源,計算瞭準高速列車以不同的速度通過鋼觔混凝土連續樑橋的振動反應.與測試結果比較,本文的計算結果是比較滿意的.

The train and bridge are considered as a whole system. According to the random vibration energy theory, by taking the artificial hunting curves and the actual measured hunting curves of the train frame as the transverse excitation source, the vibrating responses are calculated when a quasi-high-speed train runs through the reinforced concrete multi-span box girder at different speed, the results of which are found to be in satisfactory with test data.
