基于横、轴、竖加速度干扰模型的行车舒适性评价

Acceleration Noise Model Based on Horizontal,Vertical and Lateral Acceleration

由于加速度干扰可以用来描述车辆速度摆动,而车辆速度摆动又恰与乘车舒适性紧密相关,因此加速度干扰可用作乘车舒适性的定量评价指标。从横、轴、竖三个方向建立了新的加速度干扰模型,从而能为乘车舒适性做出准确的评价预测及提供合理的数学模型,达到定量分析的目的。

A measure of the velocity fluctuations during a trip is defined as the acceleration noise,and it can be used as a quantitative evaluation index for riding comfort.Acceleration noise is mainly affected by three factors：driver,road and traffic conditions.In this paper,a new acceleration noise model based on the horizontal、vertical and lateral acceleration is created.The new model not only can be used to analyze the safety of the traffic,but also can provide data for highway design.
