Abstract
Many safety regulations in the automotive engineering use impactor testing (e.g. FMVSS201 in the US; Pedestrian Protection, ECE-R21, proposal for EEVC WG13 in Europe) in the certification process. Through the increasing demand for very short development times virtual engineering has become an inevitable tool.
We show a complete virtual development process for the Free-Motion-Headform (FMH) regulation (FMVSS201u), where we use a combination of self-developed and standard software. The process starts with the definition of the target-points, the possible and allowed positioning of the FMH, the detection of worst case angles, the automated generation of section cuts, the Finite-Elements (FE) analysis and the web based documentation of the results. Our self-developed tools play an important role in the FMH-positioning/worst case detection area as well as in the result analysis and documentation.
Since all impactor testing follows in principle the same outlines, we are now working on carrying over this process systematically to other regulations.
