  4. It is showed in wind - vehicle - bridge system vibration analysis that cross wind action can remarkably increase the response of bridge and vehicle. generally, the response of bridge and vehicle are increased with wind speed and train speed, one case that vehicle is on leeward side of deck is more unsafe than another case that vehicle is on windward side of deck. nonlinear factors can more influence bridge than vehicle

    風?車?橋系統耦合振動分析結果表明：考慮風的作用會顯著增加車輛和橋梁的響應；車輛和橋梁的響應總體上隨風速和車速的提高而變大；車輛位於橋道背風側時較迎風側時更為不利；非線性因素對橋梁的影響較車輛的要大。
