Abstract
TNO performed a series of well-controlled full-scale 30/mD
angled barrier tests with Volvo 343 vehicles. In addition, a series
of simplified sled tests with a Volvo 343 body mounted at angles of
15° and 19° (i.e., the angle between the longitudinal axes of
the car body and sled) were conducted. The sled tests were carried
out with a ΔV-time history obtained from the full-scale barrier
tests. Test conditions and evaluation of the dummy results for
driver and passenger were based on the new draft ECE regulation for
head-on collisions and on the proposed ISO DIS 7862E for the
simplified sled simulations of barrier crashes.
It was found that the ECE sled test procedure in itself is well
defined and feasible with minor modifications. It should be noted
that all the dummy results were low in comparison with the
performance criteria in the regulation, and so, considering the
dummy as a measuring instrument, the results are at the lower end
of its operating range. For vehicles with different ΔV-time
histories for the left and right sides during the full-scale test,
it is not possible to reproduce dummy kinematics and at the same
time all major injury parameters with a single mounting angle of
the body on the sled and one ΔV-time history. The paper presents
more details about the mounting angle and ΔV-time history
problems.
