Analysis of pedestrian passive safety with the use of numerical simulation
Treść / Zawartość
Despite of the awareness of the pedestrians' poor passive safety, the research has aimed mainly at the reduction of car occupants' accidents and fatalities. The paper proves that the decline in severe injuries of apedestrian is feasible, as far as the car front construction is pedestrian oriented. Additionally, the technical units such as frontal protection system, fitted on the car, should at least comply with the current regulations. The expansion of the Finite Element Method (FEM) enabled the authors to implement it to the stated problem. It encompassed the pedestrian safety in terms of a collision with the front of a motor vehicle with the frontal protection system mounted. The research procedure mirrored the car vs. pedestrian collision described in Regulation (EC) 78/2009 and (EC) 631/2009 which lays down the rules concerning the boundary conditions. The carried out virtual tests — utilizing the numerical, certified impactors - were further contrasted with the results of the physical experiment. As the consequence of the research, the authors design the frontal protection system which agrees with the current requirements. Furthermore, they managed to create their own methodology for pedestrian passive safety enhancements.
