Abstract

La présente invention concerne un système d’essais dynamique des projectiles cylindriques à chaud et à froid, destiné à être utiliser dans l’étude du comportement dynamique des matériaux à des températures variables. Le principe de cette méthode consiste à chauffer ou à refroidir un projectile puis le lancer à une vitesse donnée à l’aide d’un canon pneumatique et à le faire entrer en impact avec un obstacle rigide. Cette invention fait l'objet de deux sous-systèmes : le premier sous-système sert à chauffer un échantillon à l’aide d’une résistance électrique, tandis que le deuxième sous-système permet de refroidir cet échantillon en faisant circuler un liquide de refroidissement. Chacun de ces soussystèmes est isolé thermiquement à l’aide d’une couche isolante. L’isolation thermique permet d'élargir les plages des hautes et basses températures qui peuvent être atteint lors des essais, dans le but d’obtenir des résultats précis et une étude balistique plus efficace.The present invention relates to a dynamic test system for hot and cold cylindrical projectiles for use in studying the dynamic behavior of materials at varying temperatures. The principle of this method consists in heating or cooling a projectile then launching it at a given speed using a pneumatic cannon and making it enter into impact with a rigid obstacle. This invention is the object of two subsystems: the first subsystem is used to heat a sample using an electrical resistance, while the second subsystem allows this sample to be cooled by circulating a liquid of cooling. Each of these subsystems is thermally insulated with an insulating layer. The thermal insulation allows to widen the ranges of high and low temperatures which can be reached during the tests, with the aim of obtaining precise results and a more efficient ballistic study.
