Study Of Electric Bike And Car Collisions Based On Human Injury

The traffic condition that mix the vehicles with pedestrian is the main root of high pedestrian traffic accident rate.With the rapid economic development,China has become the world's largest possessors of electric bicycles according to statistics of China In-Depth Accident Study,the electric bicycle-automobile accidents rank only second to the number of cars pedestrian accidents and which has become the second largest road traffic accidents.Therefore,the electric bicycle-Car accidents become one of most important of road safety research now.At the same time,it has an important significance of the social and economic sense to carry on such kind of research.In this paper,the main object of this research is the typical accident of the electric bicycle-car accident.Using LS_DYNA,THUMS4.0,vehicles and bicycles CAE models to build the typical accidents model.To do this research mainly from the three aspects of study of electric bike-carcollision:1?Doing mathematical statistics,logistic regression analysis for the data of CIDAS project traffic accident investigation to summed up the characteristics of electric bicycle-car collision and personal injury.Electric bicycle-car accidents in carsh focused on the speed 30-50 km / h,the typical type of the accident is frontal collision of car accident.Occupant injuries,mainly from the impact point of the airbag explosion caused by the car.The injury of cyclists mainly from the car collision.2?According to the characteristics of electric bike-car collision,personal injury cases to build traffic accident simulation model to study the kinematic response and injuriesmechanism of driver and rider.In the low-speed electric bicycles-car traffic accident,the car occupant movement is not obvious,and the seat belt is sufficient to protect the safety of vehicle occupant.At the same time the airbag does not have to burst.The injury of Rider mainly from automobile engine hood panel and windscreen.3?From the perspective of the protection of people,according to the personnel injury characteristics and the airbag mechanism in traffic accidents to study the various parts of the bike-car crashes in vehicles overload the impulse response characteristics.In Electric bicycle-car crash traffic accident,improving sensor mounting position and ACU pulse analysis capability,which can avoid the car airbag mistaken action.When develop pedestrian airbag,can take pedestrian-car collision and the electric bicycle-car collision into consideration.In this paper the research about personal injury the traffic accident canprovide reference to limit traffic speed,vehicle structure designed,protect pedestrians,cyclists treatment and so on.About car airbags mistaken action research,can provide an effective basis for the calibration of car airbags research;Effect of pedestrian safety airbag provide research ideas about the develop of pedestrian airbag.
