Parameter sensitivity analysis of two-dimensional vehicle impact model

Based on the error analysis theory of linear equations, the equation for estimating the upper bound of error for two-dimensional vehicle impact model is derived. Sensitivities of some important governing parameters, i.e., the mass and position of impact center, are analyzed through a numerical case. Results show that errors of solutions induced by small disturbance of mass parameters are small, while those of impact center parameters are large conversely. The principle of adjustment of impact center parameters is given. Conclusions obtained have certain referential value for parameters adjustment.
