Appendix 1 General conditions required from virtual testing methods
1. Virtual test pattern U.K.
The following scheme shall be used as basis structure for describing and conducting virtual testing:
purpose;
structure model;
boundary conditions;
load assumptions;
calculation;
assessment;
documentation.
2. Fundamentals of computer simulation and calculation U.K.
2.1. Mathematical model U.K.
The mathematical model shall be supplied by the manufacturer. It shall reflect the complexity of the structure of the vehicle, system and components to be tested in relation to the requirements of the regulatory act and its boundary conditions.
The same provisions shall apply mutatis mutandis for testing components or technical units independently from the vehicle.
2.2. Validation process of the mathematical model U.K.
The mathematical model shall be validated in comparison with the actual test conditions.
To that effect a physical test shall be conducted for the purposes of comparing the results obtained when using the mathematical model with the results of a physical test. Comparability of the test results shall be proven. A validation report shall be drafted by the manufacturer or by the technical service and submitted to the approval authority.
Any change made to the mathematical model or to the software likely to invalidate the validation report shall be brought to the attention of the approval authority which may require that a new validation process is conducted.
The flow chart of the validation process is shown in Appendix 3.
2.3. Documentation U.K.
The data and auxiliary tools used for the simulation and calculation shall be made available by the manufacturer and be documented in a suitable way.
3. Tools and support U.K.
At the request of the technical service, the manufacturer shall supply or provide access to the necessary tools including appropriate software.
In addition he shall provide appropriate support to the technical service.
Providing access and support to a technical service does not remove any obligation of the technical service regarding the skills of its personnel, the payment of licence rights and respect of confidentiality.
