The flexible pedestrian legform impactor simulating only a lower limb of a pedestrian, therefore, cannot adequately simulate the bending load generated on a lower limb of pedestrians due to the lack of representation of the upper body in a collision with a vehicle, especially for which has a high‐bumper.
However, no one has developed an advanced pedestrian legform impactor (finite element model and/or actual test tool) which can be applicable to all types of vehicles regardless of the bumper height through quantitative validation process using well validated human full‐body finite element model and wide variety of low‐bumper and high‐bumper vehicles.
In this study, we developed an advanced pedestrian legform impactor prototype finite element model by improving specifications of the flexible pedestrian legform impactor finite element model as well as by adding a biofidelic simplified upper body part finite element model. Then, we evaluated its biofidelity by the comparison of injury measures between the advanced pedestrian legform impactor prototype finite element model and a well validated human full‐body finite element model quantitatively under the collisions with 18 types low‐bumper and 18 types high‐bumper simplified vehicles.
As a result, we confirmed its high biofidelity under the above conditions quantitatively.
