Abstract

The Japan Automobile Research Institute and the Japan Automobile Manufacturers Association, Inc., have been developing a biofidelic flexible pedestrian legform impactor (Flex-PLI) since 2002, and its latest version is called Flex-GT-prototype. Flex-GT-prototype has flexible construction like human lower limb and is equipped with many sensors to evaluate the severity of pedestrian lower limb injuries in multiple locations. In this study, an FE Flex-GT-prototype model was developed, and its fidelity to an actual Flex-GT-prototype was verified at various evaluation conditions.
