Abstract:  A finite element front-to-side collision model of two Ford SUVs was developed to determine the worst condition of the crashworthiness of an SUV body near driving seat when the car encounters a front-toside collision from another SUV of same model at a certain speed by referring to the requirements of the 2018 China New Car Assessment Program (C-NCAP) and by using HyperWorks and LS-DYNA software, and the intrusion data as well as their distributions of the side components near driving seat of rest car were calculated in simulation when the side of the car was collided at 6 positions by striking car of 50 km/h speed in 4 directions. The results show that when a front-to-side collision of two Ford SUVs happen and the colliding speed is certain, the maximum intrusions of the side components near driving seat of struck car occur in the condition that the colliding angle is near 120° and the collided position is within the range from regulation-stated site to 200 mm ahead of the site, namely the crashworthiness of struck SUV body near driving seat appears the worst in such condition.
