摘要
利用ADAMS/Rail多体动力学软件建立CRH5拖车动力学仿真模型,通过在直线轨道上施加轨道激励来分析其临界速度、车体最大横向和垂向加速度;在曲线上分析脱轨系数、轮轴减载率和轮轴横向力,进而评估CRH5拖车的曲线通过能力。计算结果表明:CRH5拖车具有足够的运行稳定性、安全性、乘坐舒适性和良好的曲线通过性能。
Using multi-body dynamics software ADAMS/ Rail, this paper establishes the dynamic simulation model of CRH5 trailer. Through a track incentive on the straight track, it analyzes the critical speed and the body＇s largest lateral and vertical acceleration. By analyzing derailment coefficient, axles load reduction rate and axle lateral force in the curves, it assess CRH5 trailer＇s curving capacity. The results show that the CRH5 trailer has sufficient operational stability, security, comfort and good curving performance.
