FRONTAL IMPACT AGAINST ORTHOGONAL OR 30 DEG BARRIER?

CRASH FRONTAL A 0 DEG OU 30 DEG?

Details are given of the results of frontal impact tests against a rigid barrier at 0 degrees (barrier perpendicular to vehicle axis), and 30 degrees (barrier at 30 degrees with respect to the horizontal plane). A third impact test was conducted at 0 degrees, but against an indented barrier. The vehicles employed in the tests were three Opel cars of differing size and unladen weight (800, 1000 and 1250 kg). All tests were carried out with conventional three-point seat belts and with modern and reliable dummies. The frontal impacts at 50 km/h, carried out for the three different types of crash tests, showed decelerations varying as follows: when colliding frontally against a 30 deg or offset barrier, the three models showed smaller decelerations and a longer impact duration. With the collision against the 30 deg barrier, the maximum value of deceleration of the vehicle lasted about 20 ms longer than with the collision against a 0 deg barrier. The offset barrier shows a maximum deceleration which is very similar to that occurring against a 0 deg barrier, but with a longer duration. It was established that there is a correlation between the degree of local and permanent deformation and the seriousness of injuries.
