基于乘用车型平顺性分析的新指标 ———汽车综合振动舒适度Cgv
A New Index for Ride Quality Analysis of Automobiles: the Coefficient of General Vibration
-
摘要:提出了一种新的可用于乘用车开发的平顺性预测分析指标Cgv,并以长安车为例,给出了在获取Cgv指 标时,所遇到的有关速度、位置、路面比例和人机因素等诸项加权系数的确定方法,从而使概念车平顺性预测更 加合理。Abstract:This paper puts forward a newindex: the coefficientofgeneral vibrationCgv—for evaluating au- tomobiles’ride quality. Taking a Changan bus as an example, it presents the methods of determining the weighted coefficients of velocity, location, road proportion and anthropological factor,etc., which are to be used in obtaining the index ofCgv. These methods can make it more convenient and reasonable to predict the ride quality of a concept automobile.
