Crashworthiness Analysis of Finite Element Truck Chassis Model Using LS-DYNA

This paper presents a detailed multi-purpose finite element model of a light duty truck chassis and evaluates this model in computational simulations of full frontal, offset frontal, and corner impacts. The simulation results are analyzed which correctly describe the characteristics and performance of a truck chassis during under impact scenarios. Through the validation and computational simulations, the presented model is proved to be computationally stable, reliable, repeatable, and useful for vehicle crashworthiness analysis. LS-DYNA is used for finite element modeling and crashworthiness analysis
