研究目的：高速铁路线路线形引起的车辆振动响应主要集中在1 Hz以下的低频范围内，为了有效区分轨道不平顺等引起的车辆振动，从乘坐舒适性角度评价线路线形的合理性、确定线路参数的取值，本研究针对纵断面坡段长度引起的舒适性问题，应用国际标准ISO 2631中的基于不同频段的舒适性评价方法对0.02~4 Hz和0.5~80 Hz两个频段内的车体垂向振动响应分别进行晕动感（运动病，motion sickness）和舒适度（comfort）指标的评价。
研究结论：（1）夹坡段长度对竖曲线起终点引起的振动叠加有较大影响，当夹坡段长度大于200 m时，振动可有效衰减，避免叠加；（2）竖曲线激发的垂向主要振动频率与运行速度及坡段长度有关，且可能位于晕动易感频段内；（3）纵断面设置引起的晕动及舒适度问题主要受坡度代数差和夹坡段长度影响，综合考虑振动叠加和低频晕动易感频段的影响，给出了夹坡段最小长度的合理取值；（4）本研究提出的应用基于ISO 2631的低频晕动感评价方法可为高速铁路线路线形研究提供更为可靠的手段。
Abstract
Abstract：Research purposes： The frequency distributions of the vibration excited by track alignment of high-speed railway are mainly below 1 Hz. In order to distinguish the vibrations excited by track alignment from those excited track irregularity and so on, evaluate the comfort and determine the parameter of track alignment, the evaluation of the motion sickness and ride comfort caused by track vertical grade sections is performed with the frequency distributions 0.02~4 Hz and 0.5~80 Hz, respectively, based on the comfort assessment method proposed by ISO 2631.
Research conclusions：(1) The length of the intermediate grade section between vertical curves has a great impact on the overlap of the vibration excited by the beginning and ending of vertical curves, and the vibrations can be attenuated remarkably and the vibration overlap can be avoided when the length of the intermediate grade section is longer than 200 m. (2) The vibration frequencies aroused by vertical curves are related to the running speed and the length of grade sections, and may be in the ranges of the frequency bands of motion sickness. (3) The motion sickness and ride comfort caused by track vertical alignment are mainly influenced by the algebraic difference between adjacent gradients of adjacent grade sections and the length of intermediate grade sections, and the minimum length of the intermediate grade section are proposed taking the vibration overlap and motion sickness into account. (4) The comfort assessment method proposed in this paper based on the method for low frequency vibration proposed by ISO 2631 can be applied to the analysis of the track alignment of high-speed railway.
