Previous researches have revealed that both extrinsic factors, e.g. DriversвЂ™ reactions upon critical crash conflict right before the accident may determine the severity of accident consequences in a large extent.

#REAR END ACCIDENT SIMULATION HOW TO#

Results may provide a new methodology to quantitatively evaluate driving behaviors and serve as a significant guiding step towards collision avoidance for autonomous driving vehicles.Д¬itation: Zhang W, Cao J, Xu J (2017) How to quantitatively evaluate safety of driver behavior upon accident? A biomechanical methodology. Meanwhile, high impact velocity also increases the sensitivity of WIC under different collision positions and impact angles. In addition, the coupling effect can be elucidated by the fact that the difference of WIC value among three impact velocities under smaller impact angles tends to be distinctly higher than that under larger impact angles. It is revealed that the WIC (Weighted Injury Criteria) value variation law under high impact velocities is quite distinct comparing with the one in low impact velocities. Furthermore, based on the coupling of FE and MB, parametric studies on various crash scenarios are conducted. Secondly, a driver cabin model is extracted and described in the well validated multi-rigid body (MB) model to compute the value of weighted injury criterion to quantitatively assess driversвЂ™ overall injury under certain circumstances. Firstly, this paper constructs representative numerical crash scenarios described by impact velocity, impact angle and contact position based on finite element (FE) computation platform. These forces and loads can then be compared to known load tolerances of individuals, thus determining whether the claimed injuries are in fact consistent with the impact.How to evaluate driver spontaneous reactions in various collision patterns in a quantitative way is one of the most important topics in vehicle safety. Depending on the results of the reconstruction, we may then perform a biomechanical simulation of the occupants of the struck vehicle, to determine the forces levels they would experience. We can reconstruct the accident, determining the speeds of the vehicles and the forces and loads placed on the occupants, as well as the changes in speeds of the vehicle as a result of the collision. Our engineering experts can determine whether these claimed injuries are consistent with the observed damage (or lack of damage) to the vehicles. Insurance literature sources claim that 1/3 of cases involving claims of whiplash and other injuries from low-speed impacts are fraudulent, yet, there is a body of research indicating that low speed impact involving non-damaged vehicles can lead to permanent injury. Nevertheless, the occupants of the struck vehicle often complain of injury including whiplash, or neck, shoulder and back pain after the accident. Low speed rear-end impacts often result in minimal or no damage to the vehicles involved.
