Abstract

This paper contains the results of 20 cadaver pedestrian tests in which the pedestrian is impacted by a car platform fitted with an adjustable bunper. It shows the effect of bumper height and impact speed on pedestrian leg kinematics, pedestrian leg injuries, and bumper/leg forces, and it includes a method for determining the equivalent mass of the leg during the impact.

The finding contained in this paper would help to determine the parameters necessary for designing a pedestrian leg protection sub system test.
