摘要
采用边界条件法,提出满足连接圆曲线与圆曲线的新型缓和曲线,建立三种不同的计算工况,利用MATLAB数值计算分析列车以高速通过不同曲曲连接方式对乘车舒适性的影响,采用通用的机械动力学/运动学仿真分析软件Universal Mechanism(简称UM)软件进行动力仿真,通过理论计算与仿真分析得出新型缓和曲线较三次抛物线少了两个连接点(缓直点和直缓点),对舒适性有较好的改善,为高速铁路缓和曲线的选择提供借鉴。
Based on the boundary condition method,the new transition curve which connect circular curve with circular curve is obtained.By using the MATLAB,the effect of different connection types of the circular curve with circular curve on comfort is analyzed in three different working conditions.The dynamic simulation is realized by adopting the Universal Mechanism（abbreviation for UM）,which is universal mechanical dynamics/kinematics simulation software.By the calculation of theoretical and analysis of simulation,the new transition curve has less two connections than others so that the comfort has been improvement.
