There are two actual motor vehicle collision test regulation systems,i. e. FMVSS in U.S. and ECE in Europe,in which FMVSS208 and ECER94 are frontal impact test regulations and FMVSS214 and ECER95 are side impact test regulation.
The process of establishing and evaluating equation of motion for vehicle impact system were analyzed, as well as measuring methods of stress and strain for large deformation in contact impact . The front impact between the car and rigid wall was simulated according to our national central collision approach- CMVDR 294. According to the result of simulation, the crashworthiness for front impact was appraised, which can help to improve the crashworthiness.
The autopsy revealed evidence of hyperextension of the neck due to frontal impact, congenital occipitalization of the atlas accompanied by basilar invagination of the odontoid process and atlanto-axial diastasis.
This paper describes the results of computational simulations of a frontal impact to the head and the predicted development of coup and contrecoup contusion (i.e., at and opposite the site of impact, respectively) within brain tissue.
Compressive and tensile strains were predicted at the coup and contrecoup sites for a simulated frontal impact event by means of a simple elastic analysis.
Yet, volunteer studies of the cervical muscular response and head-neck kinematics to frontal impacts are uncommon, and specifically, the effect of an offset (anterolateral) frontal impact on the resultant muscle responses is unknown.
Cervical intervertebral disc injury during simulated frontal impact
High performance circuit vehicles such as Formula I and Indy cars, require to have a structure in front of the survival cell that efficiently absorbs impact energy in the event of a frontal collision.
The author published such a traumatic rupture of the mucous membrane of the oesophagus, when the multiple ruptures-beside other serious injuries-resulted on the occasion of the frontal collision of the driver.
The subject claimed to have been driving with his left index finger inserted through a hole in the spoke of his steering wheel and was subsequently involved in an offset frontal collision with a tree.
We induced and observed the frontal collision of two growth cones on narrow lanes.
This role becomes even more important as the number of advanced driving assistance systems (e.g., frontal collision warning, night vision support, parking aids, adaptive cruise control) increases.
