We present a lumped parameter model (LPM) for improving vehicle crashworthiness analysis. The novel methodology divides the event into two phases: until maximum crush and when the vehicle starts pitching forward. We built a three degrees of freedom (DOF) model for the analysis of a crash event supporting the vehicle development process. The model has been validated against the National Highway Traffic Safety Administration (NHTSA) finite element (FE) simulation of a truck and a sedan. The LPM shows good correlation with the FE test data. A parameter variation study, changing the thickness of the metal parts by 10% and 20%, is presented to improve the vehicle crash performance resulting in the reduction in pitching of the vehicle. The Simulink based simulation captures the change in the performance confirming the reliability of the model to predict event kinematics.
