This study has investigated a vehicle lumped parameter model (LPM) in frontal crash. There are several ways for determining spring and damper characteristics and type of problem shall be considered as system identification. This study use genetic algorithm (GA) procedure, being an effective procedure in case of optimization issues, for optimizing errors, between target data (experimental data) and calculated results (being obtained by analytical solving). In this study analyzed model in 5-DOF then compared our results with 5-DOF serial model. In this paper, the solution method of crash equations for lumped parameter is investigated in discrete analysis method and presented a general solution with the help of numerical solution.
