MATHEMATICAL MODEL OF HUMAN BODY HEAD AND THORAX INJURY LEVEL SIMULATION FOLLOWING THE MOTOR VEHICLE - PEDESTRIANS COLLISIONS

摘要

The impact velocity and motor vehicle frontal structures, including geometry and rigidity, have proved to be important factors that produce trauma. The paper hereby analyzes the impact between the motor vehicle and the bi-dimensional pedestrian. The motor vehicle has a constructive configuration provided with a double bumper. The second bumper is positioned under the first bumper and it is withdrawn backwards to a certain degree. The bumpers positioning heights, the impact force distribution on the two bumpers will be varied whereas the total impact force remains constant, and the velocities imprinted at the pedestrian thorax and head will be calculated. The motor vehicle rolling condition does not consider pitch movements.
