physical contacts between parts of the vehicle shall be taken into account in the mathematical model.

       4. Evaluation of the simulation

       4.1. When the stated requirements for the simulation program are met, the simulation of the changes in geometry of the interior structure and comparison with the geometrical shape of the residual space can be evaluated as defined in the paragraphs 5.1. and 5.2. of this Regulation.

       4.2. If the residual space is not infringed during the rollover simulation, the approval shall be granted.

       4.3. If the residual space is infringed during the rollover simulation, the approval shall be refused.

       5. Documentation

       5.1. The report on the simulation shall contain the following information:

       5.1.1. all the data and information stated in paragraph 1. of this annex,

       5.1.2. a drawing showing the mathematical model of the superstructure,

       5.1.3. a statement of the values of angle, velocity, and angular velocity at the unstable equilibrium position of the vehicle and at the position of first contact with the ground,

       5.1.4. a table of the value of the total energy and the values of all its components (kinetic energy, internal energy, hourglass energy), at time increments of 1 ms covering, at least, the period from first contact with the ground until the maximum deformation is reached,

       5.1.5. the assumed ground friction coefficient,

       5.1.6. plots or data which show in an appropriate way that the requirements specified in paragraphs 5.1.1. and 5.1.2. of this Regulation are met.  This requirement can be satisfied by the provision of a plot, against time, of the distance between the inside contour of the deformed structure and the periphery of the residual space,

       5.1.7. a statement of whether, or not, the requirements specified in paragraphs 5.1.1. and 5.1.2. of this Regulation have been met,

       5.1.8. all the data and information necessary for the clear identification of the vehicle type, its superstructure, the mathematical model of the superstructure, and the calculation itself.

       5.2. It is recommended that the report also contains plots of the deformed structure at the moment when maximum deformation occurs, giving an overview of the superstructure and regions of large plastic deformation.

       5.3. At the request of the technical service, further information shall be provided and included in the report.

APPENDIX B
          1. DEFINITIONS
              1.                                    "Passenger compartment" means the space intended for passengers' use excluding any space occupied by fixed appliances such as bars, kitchenettes or toilets.
              2.                                                  "Driver's compartment" means the space intended for the driver's exclusive use and containing the driver's seat, the steering wheel, controls, instruments and other devices necessary for driving the vehicle.
              3.                                    "Residual space" means a space to be preserved in the passengers', crew and driver's compartment(s) to provide better survival
