Comparison of Kinematics of Different Combinations of Bicyclists and Impact Vehicles 2020-01-0932

This study focusses on new head protection evaluation procedure for bicyclists as proposed by BASt in recent publications. This paper is focused on change in kinematics of a bicyclist when different shapes of vehicle front-end impact with different bicyclists at intersection. Bicycle and Bicyclist FE models are developed using side impact dummies and HBMs (GHBMC). Bicyclist’s head kinematics and head injury are analyzed in detail. It is found that (a) existing Pop-up vehicles are effective (b) Overall kinematics of the bicyclist will be more influenced by the relative orientations of the two legs while pedaling at the time of impact than that of a pedestrian while walking and (c) the relative position (difference in height) of BLE (bonnet leading edge) and CG of the bicyclist from ground especially the hip of bicyclist is one of the most influential parameter for WAD, the distance of the impact point of the head from ground.
