This work analyses blunt abdominal trauma produced by driver–handlebar collision, in low speed two-wheel accidents. A simplified dynamic model is introduced, whose parameters have been estimated on the basis of cadaver tests.This model allows calculating the peak impact force and the abdominal penetration depth; therefore the likelihood of occurrence of serious injuries can be estimated for different masses of contacting bodies and different speeds. Results have been checked against literature data and true-accident reports.Numerical simulations demonstrate that serious injuries (AIS>3) can occur even at low speeds (<20 km/h), therefore the design of protective clothing is recommendable.The model can allow both the analysis of true accident data and the virtual testing of protective equipment in the conceptual design phase.
