道路线形是行车安全舒适性的重要因素,在分析车辆行驶速度摆动大小对行车安全舒适性影响的基础上,提出了加速度干扰对舒适性的评价。根据道路平面线形的特点,建立了在直线、缓和曲线、圆曲线路段上的加速度干扰模型,通过仿真实例定量分析了加速度干扰在不同行驶速度、曲线半径情况下的变化趋势,以加速度干扰分析不同线形路段条件对行车舒适性的影响程度。结果表明:加速度干扰为车辆行驶舒适性的评价提供了新的方法,可为道路线形设计和优化提供参考依据。
Road alignment is an important factor in the safety of driving safety. Based on the analysis of the impact of vehicle running speed swing on the safety of driving safety, the evaluation of comfort by acceleration jamming is proposed. According to the characteristics of the roadway plane shape, the acceleration disturbance model in the straight line, the moderate curve and the circular curve section is established. The variation tendency of the acceleration disturbance at different traveling speed and curve radius is quantitatively analyzed by the simulation example. According to the acceleration disturbance analysis Degree of influence of linear road conditions on driving comfort. The results show that the acceleration disturbance provides a new method for the evaluation of vehicle ride comfort and can provide a reference for the design and optimization of road alignment.
