摘要: 公路行车舒适性与平面道路线形密切相关,在分析车辆在不同道路线形下运行特性的基础上,提出采用加速度和加速度变化对道路平面线形舒适性评价的方法,阐述横向加速度、轴向加速度与舒适性的关系及评价指标。通过分析加速度的变化对舒适性的影响,建立加速度变化率模型和加速度干扰模型。用加速度干扰表示速度摆动大小和变化频繁度,给出在直线、缓和曲线、圆曲线路段上加速度干扰的离散化模型。通过对不同道路线形的实例仿真,定量分析加速度变化率对舒适性的影响,以加速度干扰大小分析不同线形路段条件对行车舒适性的影响程度及变化趋势,并针对不同道路线形给出提高舒适性的改善方法。仿真结果表明,该评价方法为检验道路平面线形舒适性提供了参考依据。

Abstract: Highway ridding comfort and road alignment are closely related. A new method that evaluates the comfortableness of highway plane alignment with acceleration and acceleration change is put forward based on the analysis of the vehicle running characteristic under different road alignment. The relatioship among the axial acceleration, lateral acceleration and comfortableness and the evaluation index are expounded. The acceleration changing rate model and acceleration noise model are deduced through the analysis of the influence of change acceleration to ridding comfort. The acceleration noise is used to measure the change size and oscillation frequency of speed, and the discretization model of acceleration noise on the straight, cyclotron and circular curve segment are deduced. A simulation example with different road alignment is given, and the influence of acceleration changing rate to the ridding comfort is analyzed. The changing trend of the acceleration noise is also analyzed on the different plane alignment roads, and the methods of improving the riding comfort are given. Results show that it is a new evaluation method for riding comfort, which provides a reference for the inspection and evaluation of the comfortableness of road geometric alignment.

Key words: road alignment, acceleration change, acceleration noise, changing rate of acceleration, ridding comfort
