利用数理统计方法,对409辆在用奥迪100轿车制动性能台试验测所得大量样本数据进行统计分析,揭示了该型轿车8项制动性能的统计特征和内在规律性,建立了相应的分布密度函数和分布函数模型。模型公式可以对制动性能的分布情况和相关概率进行准确的描述,计算结果与实测数据高度相符。本文研究还指出了车辆制动性能等方面存在的一些问题并提出了有针对性的改进措施和建议。
Using mathematical statistics, a statistical analysis was made on a large number of sample data of 409 cars tested on the brake performance of the Audi 100 sedan, revealing the statistical characteristics and internal regularities of the eight braking performances of the sedan, and establishing the corresponding distribution Density function and distribution function model. The model formula can accurately describe the distribution of braking performance and related probabilities, and the calculated results are in good agreement with the measured data. The paper also points out some problems existing in vehicle braking performance and puts forward some corresponding improvement measures and suggestions.
