J0120103 Numerical Simulation of a Seat Belt under the Dynamic Loading

Abstract

Dynamic behavior of a seatbelt is estimated by the numerical simulation method based on the drop weight test result of the seat belt under the pre-tension force. Material property of the seat belt to simulate dynamic behavior is identified through iterative simulations changing its Young's modulus value. The effect of mesh size of the simulation model on the simulation results is also considered. As results of this study, a modelling method including material property and mesh size are presented.
