Abstract: The paper presents verification and validation procedures for the originally developed FE model of a paratransit bus, which was built for rollover test simulation. Verification of the FE model is primarily performed through analysis of the energy balance during rollover test. Series of validation experiments were designed and performed in hierarchical (multi-scale) manner. The verified and validated FE model was used to perform sensitivity analysis of the bus response to changes in material properties as well as initial conditions of the test. A measure named Deformation Index (DI) was proposed as a new quantifier of the overall deformation for easier interpretation and comparison of the rollover test results. Safety margin of the bus is estimated based on this new concept.
