关 键 词：e-bike rider parametrization kinematics and injury response test & evaluation regulations
摘 要：To explore the kinematics and injury response of the rider’s head after the collision with the vehicle,and to determine the test and evaluation boundary for its *** accident involving an e-bike was reconstructed based on an automatic operation framework,then the reliability of the reconstruction model was verified from comparisons of rider’s kinematics,the rest position of three participants,and injury with accident ***,a total of 1296 parametric cases were performed by the automatic operation framework,which was based on the validated model with a full factorial experimental design according to the collision boundary such as velocity,position,and angle from ***,a data set with 1005 valid cases were used to discuss the distribution patterns of the head’s kinematics and injury response when colliding with the vehicle such as initial impacting time,linear and angular velocity,WAD,and also for head injury criteria(HIC).The results show that WAD is positively correlated with the size of the rider and vehicle *** head contact points on the vehicle are located before WAD2100,and WAD1100-1600 should be considered significant for riders’ protection.92 % of the head impacting linear velocity are lower than 50 km/h,78 % is less than 40 km/*** collision angle of50-70° accounts for 62%,and the average angle of 5,50,95 are 57°,61°,62° *** subsystem impactor,within test area of WAD1000 ～2100 and with impacting velocity of 40 km/h and angle of 650 in current pedestrian protection regulation,seems to be applicable to the boundary of test and evaluation for SUV to e-bike riders.82% of cases with head initial collision time are less than 140 ms,and head injuries of e-bike riders mainly come from ground *** a preliminary exploration,distribution patterns of rider’s kinematics and injury response in this article will provide data and theoretical support for formulation and revision of evaluation regulations an
