Abstract

The method of calculating the head trajectory in three dimensions within the passenger compartment using the head and vehicle's acceleration and angular velocity in their respective local coordinate systems was constructed. To verify this calculation method, a crash simulation in LS-DYNA was conducted to compare the calculated result and the simulated result. The possibility of obtaining the head trajectory in the global coordinate system from the head and vehicle's acceleration and angular velocity in their respective local coordinate systems using LS-DYNA and MADYMO was also investigated. The head trajectory of a vehicle occupant with respect to the vehicle as well as the global coordinate system can be obtained using these methods.
