A study on the dynamic responses and injury mechanism of human chest in vehicle-pedestrian collisions
Artikel i vetenskaplig tidskrift, 2015

With THUMS pedestrian FE model, simulations on vehicle-pedestrian crash are conducted for four types of vehicles (medium sedan, minicar, van and SUVs) with different front-end structures at a impact speed of 20, 30, 40 and 50km/h to analyze pedestrian chest dynamic response and chest impact conditions as well as the chest deformation modes and injuries of pedestrian including rib deflections. The results demonstrate that the front-end structure of vehicle has significant effects on the dynamic response and chest impact speed of pedestrian and the stiffness distribution of vehicle front-end structure is a major factor affecting the rib deflections and chest deformation mode of pedestrian.
