Proposal of a calculation method to determine the structural components' contribution on the deceleration of a passenger compartment based on the energy-derivative method.

CONCLUSIONS: Based on the energy-derivative method, the contribution of the components' deformation on the deceleration of the passenger compartment can be calculated for various types of crash configurations more easily, directly and quantitatively than conventional methods. In addition, by combining the energy-derivative method and FIR, each structure's contribution to the occupant deceleration can be obtained. The energy-derivative method is useful in investigating how the deceleration develops from component deformations, and also in designing deceleration curves for various impact configurations.
