Abstract and keywords

In our preceding study, we developed an advanced pedestrian legform impactor prototype FE model which can be applicable to all types of vehicles regardless of the bumper height without any change of impact height from that of human. In addition, we also considered the technical feasibility to develop an actual test tool based on the specification of the aPLI PT FE model. However, no one had developed an actual test tool based on the specifications of the FE model, therefore, it was unclear that the existence of technical feasibility to fabricate an actual test tool based on the aPLI PT FE model as well as to conduct a free fright test.

In this study, therefore, we developed an advanced pedestrian legform impactor prototype actual test tool based on its FE model to confirm the technical feasibility to fabricate it as well as to conduct a free flight test using it without any issues. In addition, we evaluated its biofidelity based on the free flight test data.

As a result, we confirmed that no serious technical feasibility issues exist, furthermore, we confirmed its high biofidelity under free flight test conditions against low‐bumper and high‐bumper actual simplified vehicles.
