Research on the Effect of Seat Height on Cyclists' Dynamics Response in Vehicle-bicycle Accident

doi:10.3901/JME.2018.21.081

Abstract

Abstract: Bicycle, cyclist and car models were built software and accident simulation tests were conducted using PC-Crash. The parameter of the bicycle's seat height is introduced to study the injuries of cyclists, then the cyclist injury situation is further analyzed. The impact of bicycle seat height parameters on the cyclist's head and lower limb injuries in typical crash accidents are analyzed, and corresponding mathematical models are established. Finally, the reliability of the models are verified through real accident cases. The result of the simulation test shows that when the front middle of the car collides with the bicycle with a lower seat height, the rider's head collision position is mainly concentrated in the upper part of the hood; As the height of the seat increases, the head collision position gradually moves up to a position close to the upper border of the windshield; The influence of the seat height of the bicycle on the cyclist has different characteristics depending on the type of vehicle; At different collision angles, the cyclist's dynamic responses corresponding to different bicycle seat heights are different; the risk of head injury and lower limb fractures is related to the bicycle seat height.

Key words: accident reconstruction, dynamics responses, PC-crash, the height of bicycle seat, vehicle-bicycle
