Abstract

This study presents a set of closed form analytical solutions to the calculated energy absorbed during vehicle crushing as a result of a change in any singular crush depth for the general case of the N-point equally spaced force-crush model. The equations derived are for the case of the change in crush depth for either of the endpoints of the profile or for a change in crush depth for one of the internal points. A worked example is provided to show the correct method of implementation for the subject formulation. The results from this study show that the change in absorbed energy secondary to the change in crush depth at any particular index in the profile was dependent not only upon the crush depth changed but also the adjacent crush depth. For any given amount of change in the crush depth for a given initial value, the change in absorbed energy was greater for an internal node when compared to an external node.
