The Swedish National Road Administration presented a new design for terminals of roadside guardrails, i.e. a flared guardrail terminal mounted on the inner embankment of a ditch. The flared guardrail terminal was modeled and two vehicle models were modified with LS-DYNA to simulate an oblique impact situation. The goal of the simulations was to improve the vehicle models by refining their wheels and steering-suspension systems for better prediction and reproduction of the vehicle behavior during oblique collisions with guardrails. The refined front wheels and steering-suspension systems affected the impact behavior of the vehicles due to wheel-post impacts. A vehicle model needs these refined systems to improve oblique impact analysis with guardrails.
