摘要

摘要: 基于8自由度人椅动力学模型和31自由度车辆模型建立人-车-桥耦合系统,车辆与轨道桥梁通过轮轨接触力及位移协调条件耦合,建立人-车-桥耦合振动方程,采用Newmark-β法对方程组进行求解。对国产300 km/h动力分散式列车的过桥行走过程进行分析,采用乘坐舒适度指标对人体振动舒适性进行评价,并讨论了轨道不平顺等级、车速、乘客数量以及乘客位置对人体舒适程度的影响。

Abstract: Based on an 8 degree of freedom human-seat dynamic model and a 31 degree of freedom vehicle model,a human-vehicle-bridge coupled system was established. The vehicle and the bridge were coupled by wheel /rail contact force and displacement coordination condition. The coupled equations of the system were built and were solved by Newmark-beta method. The running process of the 300 km /h railway vehicle on the bridge was simulated and the human vibration comfortableness was evaluated with the riding comfort value. The effects of track irregularity,running speed,number and location of passengers were also discussed.
