摘要
曲线半径是确定线路容许速度、曲线超高、曲线正矢、曲线加宽、曲线建筑限界加宽、缓和曲线长度等要素的重要参数。按35自由度的车辆模型,讨论曲线梁的车桥耦合振动问题,以32m简支梁为例研究曲率和超高对高速铁路曲线梁桥车桥耦合振动的影响。
The curve radius is one of important parameters which can ascertain line allowable speed,curve super elevation,curve versine,curve widening,curved building clearance widening and length of transition curve.The 35 freedom degree vehicle model and the 32m simple\|supported beam is used and coupled vibration of vehicle and curve beam is researched.
