摘要
为了解决车辆路面纵剪力对路面损伤的评价、车辆纵振平顺性的描述等难题 ,提出了车辆纵振路面谱这一概念。路面不平造成了车辆垂向和纵向的振动 ,使它与垂向路面谱共同产生。定义了车辆纵振路面谱的数学表达方法 ,设计了用五轮仪测量纵振路面谱的试验 ,对青 -黄高速公路某段进行了实测。经数据回归分析 ,该路段垂向路面谱对应的路面级别为C级偏优 ,纵振路面谱为B级偏优。
For solving the problems such as describing the longitudinal compliance of vehicle and evaluating the pavement's damage by the longitudinal shear force between vehicle and pavement,the paper puts forward the concept of vehicle longitudinal vibration road spectrum Road roughness results in vehicle's vertical and longitudinal vibration,which happen together with the vertical road spectrum This paper also defines its mathematic expression and designs the test with fifth wheel device Through actual measurement on Qing-Huang highway and data regression analysis,the road's vertical spectrum belongs to C + level road and the longitudinal spectrum belongs to B + level road
