Research on Helmet Protection in Human-Vehicle Collision Accidents
In the electric two-wheeler crash accident,the second collision between the cyclist's head and the ground is an important factor causing fatal injury.As an important protective part of road traffic safety,helmet can effectively reduce the head injury of cyclists.A second impact test of the cyclist's head in a human-vehicle accident is carried out.The test results show that the faster the impact speed of the vehicle and the higher the cyclist's fall height,the greater the damage to the head impacter without wearing a helmet.Helmets can effectively protect cyclists from fatal head injuries.
