An auto manufacturer considers many collision loadcases when developing a new automobile or enhancing the performance of an existing one. These loadcases have been developed in an attempt to represent the worst-case loading conditions that typically occur in the field. Many of these loadcases can be considered “driving loadcases”; ones which tend to define portions of the vehicle structural loadpath topology or the strength or stiffness levels within it. Crashworthiness loadcases that typically drive the vehicle structural loadpaths are covered in detail within this chapter, including discussion of how the EV configuration affects the structure and how the structure might change to accommodate the demands of an EV. The material in this chapter is organized and presented with the goal of building the reader’s intuition of structural behavior in mind.
