THE CONTRIBUTION OF OCCUPANT AND VEHICLE DYNAMICS SIMULATION TO TESTING OCCUPANT SAFETY IN PASSENGER CARS DURING ROLLOVER

The quantification of occupant safety provided by a passenger car during vehicle rollover is the subject of this paper. Since existing test procedures (e.g., FMVSS 208 and FMVSS 216) aim mainly at the structural safety of vehicles, there is a lack of standardized injury criteria for the occupants. The results presented in this paper are based on the experience gained during the development of a rollover detection system. A large number of rollover simulations using the modular vehicle modeling program FASIM_C++ were conducted. This multibody simulation tool provides a three-dimensional vehicle model and includes complex mechatronic elements like hydraulic systems, actuators, sensors and electronic controllers. Using the commercial occupant simulation toolset MADYMO, occupant behavior during rollover was studied. Various accident scenarios are modeled using FASIM_C++ and the subsequent occupant behavior is analyzed in MADYMO. The paper discusses the simulation results of various rollover maneuvers and suggests requirements for a standardized rollover test procedure that focuses more on occupant safety than the existing regulations.
