Vehicle Front Structure in Consideration of Compatibility

摘要: A structure which effectively improves compatibility in a vehicle-to-vehicle frontal impact has been considered focusing on sub-frame that disperses applied force with multiple load paths. Evolved studied by CAE RADIOSS to search the possibility reduce aggressivity and improve self-protection at same time. Vehicle models used for this study were large saloon car small family without sub-frame. The had three different front structures: original, forward-extended sub-frame, original 25%-stiffness reduced structures. types of collision contained four crash modes combination lateral overlap rate difference side member height difference. With these structures modes, simulations conducted evaluate based compartment deformations, energy absorption amount, Average Height Force (AHOF). As result, it was found improved both preventing override effect through structural interaction enhancement. For covering abstract see ITRD E825082.
