Abstract
(EN)
The present invention relates to a shock resistance test apparatus for evaluating resistance to shock occurring when a projectile collides with various specimens and, more particularly, to a shock resistance test apparatus that can be applied to projectiles of various sizes or shapes and is capable of being used semi-permanently as a small piece of equipment. The shock resistance test apparatus of the present invention is characterized by being configured of: a shooting part for loading a rear end of a carrier on which a projectile is mounted; a shooting tube coupled to the front of the shooting part and having the carrier shot therefrom; and a test chamber coupled to the front of the shooting tube and having a specimen fixed therein, wherein the carrier includes a cylindrical housing having both ends open, a plurality of fixing parts coupled to the inner circumferential surface of the housing to press and fix the projectile at the center of the housing, and a loading part for sealing the rear end of the housing.

La présente invention concerne un appareil de test de la résistance aux chocs servant à évaluer la résistance aux chocs se produisant quand un projectile entre en collision avec divers échantillons et, plus particulièrement, un appareil de test de la résistance aux chocs qui peut être appliqué à des projectiles de diverses tailles ou formes et peut être utilisé de manière semi-permanente à titre d'équipement de faible encombrement. L'appareil de test de la résistance aux chocs selon l'invention est caractérisé en ce qu'il comprend : une partie tir pour charger l'extrémité arrière d'un support sur lequel est monté un projectile ; un tube de tir raccordé à l'avant de la partie tir et et à partir duquel le support est tiré ; et une chambre de test raccordée à l'avant du tube de tir et contenant un échantillon immobilisé, le support comprenant un boîtier cylindrique dont les deux extrémités sont ouvertes, une pluralité de pièces de fixation couplées à la surface circonférentielle intérieure du boîtier pour presser et immobiliser le projectile au centre du boîtier, et une partie chargement pour sceller l'extrémité arrière du boîtier.
