主成分评价法在汽车操纵稳定性评价上的应用

针对传统汽车操纵稳定性客观评价方法中评价指标间存在的相关影响和评价过程繁琐等问题.文章将多元统计分析理论中的主成分分析应用于汽车操纵稳定性的客观评价中,提出采用主成分分析法进行评价.该方法以降维为核心思想,消除评价指标间的相关性;运用SPSS软件实现评价过程,简化了评价步骤;评价结果以综合得分形式给出,一目了然.新方法虽较好的解决了传统方法中存在的遗漏,但也存在一定的局限性.现阶段只能作为一种辅助手段,作为传统评价方法的补充评价方法.

The Application of Principal Component Assessment Method in Vehicle Handling Stability Evaluation

For solving the problems, sneh as related effeels belween evaluation indexes and evaluation prueess trivial, which are in the traditional objective evaluation method of vehicle handling stability, in this paper, applying principal component evaluation method in muhivariate statistical analysis theory to do the objective evaluation of vehicle handling and stability, a new evaluation method is proposed. The core idea of this method is to reduce dimension, to eliminate the correlation between evaluation indexes; Using SPSS sof＇tware implement evaluation process, to simplify the evaluation prueedure; the evaluation resuhs are presented in the form of composite scores. The new method is better for solving the existing in the traditional method of omission, but it has some limitation. At this stage, as an auxiliary means, this method is only used as a supplement of traditional evaluation method.
