汽车碰撞兼容性由于能更好地反映真实交通事故,已发展成为被动安全研究领域中最具安全技术潜力的新技术。针对侧面冲击载荷作用下车对车的碰撞兼容性问题,从理论分析和仿真分析角度出发,研究了主要影响因素:两车质量比、汽车前端刚度特性、汽车几何特征对两车碰撞兼容性的影响。结果表明:质量比是影响两车兼容性好坏的关键因素,通过降低汽车前端变形吸能刚度和主吸能位置、提高两车碰撞接触面积等可以提高被撞击车的耐撞性和降低撞击车的攻击性,从而降低所有涉案人员损伤,提高车对车侧面碰撞兼容性。
Automotive Collision Compatibility As a better reflection of real-world traffic accidents, it has evolved into a new technology that has the potential of the safest technology in passive safety research. Aiming at the compatibility of vehicle-to-vehicle collision under side impact load, the main influencing factors are studied from theoretical analysis and simulation analysis: the mass ratio of the two vehicles, the stiffness characteristics of the front end of the vehicle, the compatibility of the vehicle geometry to the collision between the two vehicles influences. The results show that the mass ratio is the key factor that affects the compatibility of the two vehicles. The crashworthiness and the impact of the collided vehicle can be improved by reducing the deformation energy absorption stiffness and the main energy absorption position of the front end and increasing the collision contact area of the two vehicles. Car offensive, thereby reducing the damage of all involved and improve car-to-car side collision compatibility.
