The relevance of frontal car to car collisions with low lateral offset (smaller than 30%) have been investigated in several publications [1, 2, 3, 4, 5, 6]. Low offset frontal collisions showed the same relevance in occurrence and injury risk as “standard” offset crashes (represented by EURO-NCAP 64 km/h frontal crash) and fully overlapped crashes (represented by US-NCAP 56 km/h frontal crash). Up to now, no requirement (legal, consumer test or OEM in-house) takes into account this impact constellation. In low lateral offset crashes the so-called “rim-locking” effect prevents vehicles from sliding off each other and causes collapse of the passenger compartment at comparatively low collision velocities. A suitable crash test configuration for this impact scenario, was already investigated in previous research [2, 6]. A laboratory load case was proposed including a car to car frontal impact
with the following impact configuration:
Performing crash tests with such an impact constellation provides several problems:
To avoid these shortcomings, the present paper investigates possibilities to simplify the car to car test. Therefore, different moving and non-moving impact obstacles, specially designed for this purpose are investigated. By means of Finite-Element-Method (FEM) computer simulations these simplified test configurations are compared to the original proposed car to car crash test.
Suite à ces tests, les problèmes suivants ont été soulevés:
C’est pour éviter ces questions délicates que cette publication étudie des possibilités de simplifier le test véhicule-véhicule. Une analyse de différents obstacles (fixe et en mouvement) spécialement conçus pour ce genre de test a été menée. C’est grâce à des simulations sur ordinateur (utilisant la méthode des éléments finis)
