Research on design method regarding pedestrian head protection

Abstract

A reasonable simplified mode is used for head impact, and this paper does some research about the necessary crash depth by simplifying the waveform of the pedestrian head impact, the optimal waveform, which using the minimal crash depth, is calculated. Analysis of the head collision wave formation mechanism and influencing factors is also carried out. Measures for improvement in favor of the pedestrian head protection are put forward. This paper establishes the pedestrian head-form crash model, and verifies the model by head crash tests. Some measures are carried out to improve the head protection performance, the result shows the improvement measures proposed in this paper can effectively improve the pedestrian head protection.
