PEDESTRIAN PASSIVE SAFETY: FINITE ELEMENT AND MULITBODY SIMULATIONS
Abstract
The paper presents the evaluation of the pedestrian safety, during a collision with a road vehicle with the high bonnet leading edge. A Sport Utility Vehicle (SUV) was chosen to investigate the influence of vehicle front design on the pedestrian lower extremity injuries. The Finite Element Method (FEM) was utilized in order to reduce the costs and time needed to carry out a pedestrian-to-car front aggressiveness test. The virtual tests carried out by means of the numerical, certified Finite Element (FE) lower leg impactor were further contrasted with the results of the multibody (MB) simulation. While the FE impactor gives in-depth data about leg fractures and knee joint injuries, further MB simulations present the complete, post-impact pedestrian kinematics. Finally, the critical points in SUV design, in terms of pedestrian passive safety enhancement, were indicated.
