Human subject rear passenger symptom response to frontal car-to-car low-speed crash tests

Abstract

Objective: The purpose of this study was to determine whether healthy adult volunteers report symptoms following exposure to low-speed frontal crashes at low velocities. Methods: Nineteen medically screened, healthy, informed, and willing volunteers (17 men, 2 women; mean age, 37 years) were exposed to low-speed frontal crashes. All volunteers were seated in the rear seat position of the bullet vehicle. Closing velocities ranged from 4.1 to 8.3 mph (mean, 6.7 mph). For the bullet vehicle, the delta V ranged from 1.4 to 3.9 mph with a mean of 2.8 mph.Results: Eighty-eight percent of volunteers attributed symptoms of discomfort to their crash exposure. All reported symptoms were transient, and none required medical treatment. The mean duration was 1 day. Conclusions: Even at relatively low speeds, there is no lower threshold below which it can be reasonably assumed that healthy and prepared volunteer rear seat passengers will not sustain some level of minor injury in a frontal collision. Although the reported mean delta V for injured persons in real-world frontal crashes has been reported to be as high as 8.1 mph, this does not offer any insight into the minimum threshold for such injuries among all at-risk vehicle occupants.

“…Only volunteers are used in tests at speeds of up to 20 km/h. Dummies for such tests are not constructed [46][47][48].…”

Influence of repair cost on different front energy absorbing structure to automobile low-speed impact

“…In China, the injuries and death caused due to vehicles high speed impact, has been get attention. But, low-velocity collisions usual occur in crowded cities [1,2]. Low speed impact didn't get the attention of people, because no personnel injury.…”
