EVU 2013 Florence OmerovicThis paper presents the use of computer simulations as the approach of determining the possible causes of various injuries sustained by motorcyclists in traffic accidents. The main advantage of computer simulations is their ability to reconstruct the traffic accidents in three-dimensional space with the use of mathematical models of the vehicles and occupants involved. In this research several typical motorcycle accidents were simulated. For each of them, with the analysis of simulation results possible injuries of the motorcyclist were determined. These simulation results can be helpful for forensic experts in determining the cause of various impact injuries in motorcyclist victims, as well as for improving road safety. In this research, the FEM model of the motorcycle Kawasaki ER-5, car Suzuki SWIFT and Hybrid III dummy were used for simulating the motorcyclists’ accidents. Each of the dummy’s body segments was equipped with an accelerometer and load cell for measuring the accelerations and impact forces during the impact phase. Based on the literature review, several of most common motorcyclists’ accidents scenarios were determined and simulated with the use of LS-Dyna FEM software. Simulation results were then analysed to determine the loads and possible injuries on the individual body segments of motorcyclist. Simulation results were also used to determine damage to the vehicles involved in the accident and to correlate it to the impact speed, which in many cases it is difficult for forensic crash investigators to determine.
