In this study, the effect of surrounding parts on the retention force of open hood which is only maintained by safety hook at high speed driving was analyzed. Compared objects were mini MPV, mid-size coupe and submid-size hatchback, which have different hood shapes, respectively. Aerodynamic analysis was performed by PowerFLOW which is commercial software based on Lattice Boltzmann method. And structural analysis was performed by NASTRAN. Related to the effect of each part, the mass flow rate and pressure were investigated since the force is caused by the pressure difference between hood outer and inner panel. At first, the effect of the adoption, size variation, hole creation of under-cover were studied. Secondly, it was observed that there was the meaningful effect of the closing of bumper lower air intake by changing the mass flow, which imitates air shutter. Related to the heat exchanger, there was little effect of pressure drop for the range in this study. Finally, it was observed that the changing of engine size effects greatly on hood retention force.
