为获得高速公路车辆分类的量化方法,根据典型测点的各车型轴载谱数据,归纳了高速公路的主要车型,并研究了高速公路车辆分类方法。采用2个独立样本的非参数假设检验,研究了客车与各型货车前轴及单后轴的称重数据是否来自同一总体,在此基础上,采用多个独立样本的非参数假设检验方法研究了各型货车间相同轴型的称重数据是否来自同一总体。研究表明,各型货车力学特性接近,属于同一大类型;而客车与货车的力学特性差异明显,因此可将客车与货车划分为两大类型。非参数假设检验方法为高速公路车辆划分提供了量化的依据。
In order to obtain the quantification method of expressway vehicle classification, the main models of expressway are summarized according to the axle load spectrum data of each type of typical measuring point, and the classification method of expressway vehicles is studied. The non-parametric hypothesis test of two independent samples was used to study whether the weighing data of the front axle and the single rear axle of the passenger cars and the various types of trucks come from the same whole body. On this basis, the nonparametric hypothesis testing method of multiple independent samples The same type of workshop for the same type of weighing data from the same overall. The research shows that the mechanical characteristics of various types of trucks are similar and belong to the same type. However, the difference between the mechanical characteristics of passenger cars and trucks is obvious, so the buses and trucks can be divided into two types. The non-parametric hypothesis testing method provides a quantitative basis for highway vehicle division.
