W artykule przedstawiono przeprowadzone badania na podstawie sformułowanego w systemie WorkingModel 2D płaskiego modelu kierowcy. Model uwzględnia wszystkie główne części budowy ciała, ze szczegółowym odwzorowaniem odcinków najbardziej narażonych na urazy: szyjnego i lędźwiowego odcinka kręgosłupa człowieka. Model został zweryfikowany na podstawie danych literaturowych testów prowadzonych na ochotnikach w zakresie bezpiecznych prędkości przez The Naval Biodynamic Laboratory in New Orleans in USA. Model wykorzystano do przeprowadzenia symulacji zachowania się kierowcy w sytuacjach rzeczywistych wypadków komunikacyjnych: zderzenia przodem oraz zderzenia tyłem.
The article presents two - dimensional model of driver created with the use of Working Model 2D software. The model consists of every part of human body with detailed structure of cervical and lumbar spine. The parts of spine are the most exposed to injuries during accidents, especially cervical spine which injuries could cause serious consequences - paralysis or even death. The model of driver was validated on the basis of comparison of body movement in saggital plane, data from numerical simulation and from tests on volunteers performed by The Naval Biodynamic Laboratory in New Orleans in USA. Next the model was used to carry out numerical simulation for several cases corresponding to real accidents (front collision for velocity 28, 80, 120, 160 kmph, and rear collision for velocity 28, 80 kmph). The obtained results confirm that the velocity and constructions of collided vehicles also have the greater influence on human body behavior and possibility of injuries. Forces inside human body depend especially on velocity of a car at the hit moment. In a car velocity above 100kmph the passenger’s chances to survive rapidly decrease due to acting acceleration. The position of the driver in a car and the connections with internal car equipment are playing considerably less important role. Only safety belts are important for preventing situation dangerous for passenger’s security. The model could be used to analysis of other cases of accidents which assume other vehicle velocities during front and rear collisions. The researches were inspired by Sultan Bin Abdulaziz Al-Saud Foundation, from Saudi Arabia.
