Sled tests for development of HIII CAE dummy certification method

Abstract

Virtual testing has been used as complement to mechanical testing in consumer information programs such as European New Car Assessment Program (Euro NCAP) since 2009. Rapid expansion of virtual testing with additional load cases are announced by Euro NCAP and China-NCAP (C-NCAP). For this development validation of the virtual models is an important aspect. Therefore, there is a need for results from tests with clear and well documented boundary conditions that can be used for validation of the virtual models. For this purpose, tests were carried out with the generic frontal impact sled test set-up at 40kph and 56kph impact velocity with the 5, 50 and 95 anthropometric test devices (ATD) positioned as drivers. Per each ATD size and crash pulse, 3 repeated tests were run resulting in a total of 18 tests. Prior to test, the position of the ATD was 3D-scanned to enable detailed comparison of the initial position between the physical and CAE ATD model. Generally small variability in the test results was observed for the tests performed in the same configuration. All ATD readings were higher for the impact at 56kph than for the 40kph impact. Coefficient of variation (CV) rated all (50) but 16 measurements as excellent. Making it an adequate dataset for model validation.
