Abstract:The relationship between colision patterns in truck-versus-electric-two-wheeler crashes,the kinematic responses of riders,and injurycharacteristics were investigated.16 simulation experiments were constructed by using the multi-body modeling software MADYMO based on 263 scenario-related cases to analyze the colision angles and the positions.The results show that the head injury metrics (the head injury criterions (HIC)and the headangular accelerations)sharply increase when the colisionanglesexceeds 110∘ ，withthepeakingat thecollisionangleof 120∘ (theHlCof11931,theheadangularaccelerationof .When the colision position is in the central area of the truck,the cyclist's HIC (1 231~1 461) and the head angularacceleration fall within lower ranges, that means lower risk of head injury.When thecollisionoccursoneither sideof the truck,thecyclist'schest 3-msacceleration is 25.8g～121.8g ,that means a lower risk of chest injury.Therefore,both the colision angle and the collision position havea significant impact on the cyclist's kinematic response.
