| Abstract: | Based on the perturbation theory,the capability against perturbation in vehicle impact accident reconstruction models was analyzed by using three kinds of usual mathematical methods.The results showed that in case of the complicated perturbation,the process of model applied different mathematical methods have different results.The methods for this problem are set up and formulas are put forward based on the analysis of theory.Through typical vehicles impact calculation,the results are proved that it is an effective method. |
