Abstract
<div class="section abstract"><div class="htmlview paragraph">To solve the problems of ethnic size difference and model simplification in
existing research, three kinds of lower limb finite element models of adult male
with percentile 5, 50 and 95 were established based on the size characteristics
of Chinese human body.The bionic reliability of the models was verified
according to three different lower limb biomechanical experiments. Through the
simulation analysis of pedestrian lower limb with different percentiles in side
impact, it was found that in the pedestrian low-speed side impact accident, the
lower percentile human body has a higher risk of lower limb injury,especially
the injury of knee joint. The soft foam structure can play a better cushioning
and energy absorption role in the impact process. The response parameters
decrease with the decrease of percentile.In addition,the soft foam can
significantly reduce the risk of lower limb injuries when impacting the lower
limbs laterally at low speed.</div></div>
