VEHICLE MECHANICS OF INTERSECTION COLLISION IMPACT

THERE ARE TWO PHASES IN AUTOMOBILE COLLISIONS, NAMELY, THE IMPACT PHASE, WHICH IS TREATED IN THIS PAPER, AND THE AFTER- COLLISION PHASE. AS INDICATED BY FULL-SCALE EXPERIMENTS IN UNIDIRECTIONAL COLLISIONS, AND AS CONFIRMED BY SIMILITUDE MODEL STUDY IN SIDE IMPACT COLLISIONS, VEHICLES BEHAVE AS RIGID BODIES IN BOTH IMPACT AND AFTER-COLLISION PHASE. WITH THIS CONFIRMATION, THE ANALYSES OF SEEMINGLY COMPLEX INTERSECTION AUTOMOBILE COLLISION PHENOMENA BECOME POSSIBLE BY APPLICATION TWO-DIMENSIONAL IMPACT THEORIES WHICH ARE PRIMARILY BASED ON THE MOMENTUM-IMPULSE PRINCIPLE OF RIGID BODIES. AVALIABLE FULL-SCALE INTERSECTION EXPERIMENTS INDICATE THE NUMERICAL RANGE OF THE COEFFICIENT OF RESTITUTION AND THE COEFFICIENT OF FRICTION BETWEEN TWO VEHICLE BODIES IN COLLISION. /HSL/
