In vehicle design, the H point is a theoretical relative location measured in relation to specific characteristics, for example, H point to vehicle floor (H30), H point to ground (H5) and others. Based on theoretical H point automakers concept their vehicle and have to make important decisions on vehicle architectural that could result in a bad product for the future customers and during the early phase of vehicle development, one of the key design attributes to consider is in relation to the comfort of the user, so that its design and its components enable a favorable interaction with the occupant. Accessibility is one of the pillars on which this concern can be observed. Certain features such as the size of door opening and the height of the vehicle from the ground, among others, may influence the level of satisfaction of the occupants’ access.

The objective of this work is to capture the final deformed shape of a vehicle after a rollover caused by a corkscrew event (ramp). With this study, it will be possible to understand the vehicle structural behavior during this event and be able to improve the vehicle safety in this specific condition. For this proposal, it will be presented a virtual methodology using available commercial CAE tools and perform a crashworthiness analysis of the desired event. The first step is to capture the dynamic event through a Multibody analysis that represents the interaction among the vehicle tire, suspension components (Springs, Dampers, Jounce Bumper, Bushings, Stabilizer Bar etc.), vehicle structural stiffness, mass, center of gravity and inertias when exposed to a corkscrew standard ramp, that initiates the rollover event. This methodology will represent with fidelity all dynamic aspects of rollover event before the vehicle touches the ground.
