Title (EN) IMPROVEMENTS IN OR RELATING TO CONSTRUCTION TEST APPARATUS
(FR) AMELIORATIONS SE RAPPORTANT A UN DISPOSITIF D'ESSAI D'UNE CONSTRUCTION
Abstract:
(EN) Real scale investigations can be carried out on vehicle impacts using a vehicle, or part thereof, or crash barrier, tested on a large dynamic testing facility (LDTF). The LDTF includes nodes (402, 403) connected at either end of a sample under test (crash barrier 400). The forces in the bar are measured by Hopkinson output bars (404, 405; 406, 407) connected at right angles at each node (402, 403) to measure perpendicular components of a force in the barrier (400). Vehicle (401) may be equipped with additional instrumentation and used as an impactor against the barrier (400).
(FR) On peut effectuer des investigations à l'échelle réelle sur des impacts avec des véhicules, en utilisant un véhicule, une partie de celui-ci, ou une barrière de protection, que l'on teste sur une grande installation d'essai dynamique. Cette installation présente des noeuds (402, 403) reliés à l'une quelconque des extrémités d'un échantillon soumis au test (barrière de sécurité 400). On mesure les forces dans la barre, à l'aide de barres (404, 405; 406, 407) de sortie Hopkinson, lesquelles sont reliées à angle droit au niveau de chaque noeud (402, 403) afin de pouvoir mesurer les composantes perpendiculaires d'une force appliquée sur la barrière (400). Un véhicule (401) peut être pourvu d'instruments de mesure additionnels et utilisé en tant qu'élément de percussion contre la barrière (400).
