Statistical Analysis and Improvements on Car Braking Performances

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。

By means of statistical principle and braking test,this paper carries out a statistical analysis on a vast amount of braking performance sample data of 409 Audi 100 cars in use, reveals the statistical features and inherent regularity of 8 braking performances of this model car, and establishes corresponding distribution density function and distribution function models. These model formulas accurately describe the distribution and relevant probabilities of braking performance. The result tallies well with the actual test data. This paper also points out some existing problems on vehicle braking performance, and puts forward some improvements and suggestions correspondingly.
