中文摘要:

根据舒适度要求研究高速铁路平竖曲线重合地段曲线参数选取问题。基于SIMPACK分析平台建立高速铁路车线动力学模型,对平竖重合地段车辆运行舒适性情况进行计算分析,结果表明:行驶动力学所计算的欠超高和当量欠超高小于车线动力学方法确定的相应值,行驶动力学方法低估了列车运行实际舒适度;在平曲线半径较小时,欠超高量较大情况下,两种方法计算结果差别较为明显。同时,根据规范中舒适度规定,给出设置上凸和下凹竖曲线条件下最小平曲线半径值,研究可为规范标准制定提供参考。

英文摘要:

According to the requirement on riding comfort, the authors carried out the research on the issues of selecting the reasonable curve parameters at the overlapping region of vertical curve with horizontal curve. Meanwhile, after establishing the vehicle-track dynamics model of high-speed railway based on SIMPACK analysis platform, the riding comfort level of train at the overlapping region of vertical curve with horizontal curve was calculated and analyzed. The results show that, both the superelevation deficiency and the equivalent superelevation deficiency calculated by the driving dynamics method are less than they are calculated by the vehicle-track dynamics model method, so the actual riding comfort level of train is underestimated by the driving dynamics method. Furthermore, under the condition that the horizontal curve radius is smaller and the superelevation deficiency is larger, the difference between the two results calculated respectively by the two dynamics methods is obvious. The authors, also, according to the requirements on riding comfort specified in the standards, put forward the minimum horizontal curve radius values under the condition of convex or concave vertical curve. The research may serve as reference for drawing up the relevant standards.
