Abstract

Research on the evaluation method for vehicle compatibility has continued among passive safety industries in recent years. NHTSA, which has jurisdiction over automobile safety in the U.S., is studying AHOF400 as a new criteria to evaluate interaction between vehicles to improve compatibility performance. In this paper, the target value of AHOF400 was assumed to be Part581 zone, which is the front bumper height of a passenger car. A basic study was carried out using finite element modeling of an existing vehicle model and a real vehicle crash test in order to determine how to practically modify the vehicle structure of an SUV. As a result, it was determined that the height of the Front Side Member of an SUV should be lower than that of a passenger car in some cases. This is different from the original aiming point that car-to-car interaction would be improved by restriction of AHOF400, which makes the height of front end structures the same level. As a way to solve the concern, an evaluation area of barrier load cells height which is appropriate to calculate AHOF400 was studied
