| Abstract: | In order to solve quickly two-dimensional vehicle collision model based on the momentum theorem,a simple algorithm was established by partitioning of matrix.Matrix rank of the model can be reduced through partitioning of matrix,which could simplify the process of solving matrix.The analysis of a typical collision case shows that the method can calculate the car crash rapidly and accurately. |
