2. The mathematical model
The model shall be capable of describing the real physical behaviour of the rollover process, in accordance with Annex 5. The mathematical model shall be constructed, and assumptions prescribed, in such a way that the calculation gives conservative results. The model shall be built up with the following considerations:
2.1. the technical service may require tests to be carried out on the actual vehicle structure to prove the validity of the mathematical model and to verify the assumptions made in the model.
2.2. the total mass and the centre of gravity position used in the mathematical model shall be identical to those of the vehicle to be approved.
2.3. the mass distribution in the mathematical model shall correspond to the vehicle to be approved. Moments of inertia used in the mathematical model shall be calculated on the basis of this mass distribution.
