Abstract

The invention discloses a model experiment system for realizing the inclined impact of a projectile body, which is characterized by comprising a barrier plate and a projectile support for ensuring the projectile body to normally leave a bore and controlling the attach angle of the projectile body. The projectile support is made of a light fragile material, the projectile support is a cylindrical shell which is made of lightweight fragile materials, the outer diameter of the cylindrical shell is smaller than the caliber of an air gun barrel, the head and the tail of the projectile support are provided with annular bosses, a plurality of holes are arranged on the wall of the projectile support, the head of the projectile support is processed into a cone shape, and the head of the projectilesupport is provided with a projectile slot with an inclined angle consistent to the attack angle of the projectile body. The inclined model projectile body and the projectile support can freely slidein the gun barrel. The barrier plate is located between an experiment target plate and the heavy caliber air gun barrel, the middle of the barrier plate is provided with a horizontal unshelling slot,and the width of the unshelling slot is greater than the diameter of the model projectile body but is smaller than the caliber of the air gun barrel. The experiment system of the invention can be used for conveniently completing the impact experiment of the inclined projectile body with an attack angle.

Description

technical field [0001] The invention belongs to the field of model experiment research of the impact process, and in particular relates to a model experiment system for realizing oblique impact of projectiles. Background technique [0002] In the process of transportation and use of various products, it is an unavoidable problem that the product falls from a height. The drop may directly cause deformation and damage to the outer packaging box of the product, which in turn will lead to damage to the product structure and loss of function. When designing product outer packaging and product structure, their drop resistance performance must be considered. [0003] In order to investigate the anti-drop performance of the structure, the real prototype structure is often tested by freely falling on the experimental equipment such as a drop tower. However, the cost of the prototype test is high and the cycle is long, so it is not suitable to conduct a large number of tests. Therefor...
