Description

Apparatus and Method for Moving and Installing Specimen in High Velocity Propulsion Impact Testing Machine

The present invention, in a high-speed crash test apparatus for evaluating and verifying the bulletproof ability, material performance, etc. of a specimen by colliding a high-speed collider launched at a high speed against a specimen, a specimen moving and installing device used to install a specimen in a collision chamber, It relates to a method of installing the specimen in the collision chamber of the high-speed collision test apparatus using the method, specifically, allowing a specimen of considerable weight to be conveniently and stably fixed and installed in the collision chamber, and X-ray imaging in the collision chamber It relates to "a device for moving and installing a specimen for a high-speed crash test, and a method for moving and installing a specimen in a high-speed crash test device using the same" having a configuration capable of easily placing a film for it.

In order to verify and evaluate the bulletproof performance or collision performance of specimens made of various materials such as concrete members or steel panels, or the performance of other materials, bullets, etc., using a firing propeller such as a high-speed gas gun, etc. A "high-speed collision test" is performed in which the projectile is launched at high speed and collides with the specimen. A device for such a high-speed crash test, that is, a "high-speed crash test device," is a projectile propellant that imparts propulsion to a projectile by using gas pressure, a tube through which the projectile is flying, and a closed space in which the projectile collides with the specimen. The branch is configured to include an impact chamber. Korean Patent Registration No. 10-1267792 discloses an example of a relatively small-scale high-speed crash test apparatus.

In order to test the performance and fracture patterns of the specimen for high-speed collision test, the specimen must be installed in a collision chamber so as to be perpendicular to the direction in which the projectile flies. It needs to be firmly fixed and installed so as not to move horizontally in the direction. In general, the specimen for high-speed collision test is made of a material such as concrete or steel and is in many cases heavy.In the prior art, the operator directly lifts the heavier weight specimen and transfers it to the inside of the collision chamber to fix it. However, the work of transferring and fixing such a heavy weight specimen into the collision chamber requires a very large physical force, which causes the efficiency of the high-speed collision test to be lowered, and the specimen falls during the transport and fixation process, resulting in injury to the operator. There is also a high risk of safety accidents in which the specimen is damaged.

On the other hand, in recent years, when imaging technology has advanced and X-rays are taken using a high-speed camera, images of the state when the projectile collides with the specimen or when it passes through the collision chamber can be acquired. It is also important to install an X-ray irradiation device for ray photography, but it is also very important to stably install an X-ray film on which an X-ray image is projected in a predetermined position. In the conventional high-speed crash test apparatus, the operator entered a narrow space in the crash chamber and manually installed the X-ray film. The installation work of the X-ray film was very cumbersome, and the X-ray film was not installed in the correct position. There is also a problem that occurs even if it is not possible.

This process can bring a very large physical strain to the operator, and there is a great concern that the specimen (3) will be missed during the horizontal movement process, and in this case, the specimen (3) may be damaged, as well as injury to the operator. It could be.

However, in the case of the present invention, the sliding movable body 1 in the state in which the specimen 3 is installed can very easily enter and exit the collision chamber 203 by the rolling motion of the rolling wheel. That is, in the present invention, even if the specimen 3 has a large weight, it is possible to easily insert and place it in the collision chamber 203 at an accurate position without exerting a large force by the operator, and after the high-speed collision test is completed, it is very easy. The specimen 3 can be pulled out of the collision chamber 203. Therefore, in the present invention, the work of directly lifting and moving heavy things in the process of transferring and installing the specimen 3 is minimized, and accordingly, it is possible to suppress a physical strain on the worker, and furthermore, the specimen ( 3) can be effectively prevented from falling, and safety accidents such as injury to workers and damage to the specimen due to dropping of the specimen can be effectively prevented in advance.

In addition, in the present invention, it is possible to very easily install an X-ray photographing film for X-ray photographing of a specimen collision situation in a collision chamber at an accurate location, and thus, it is possible to safely and more efficiently perform a high-speed collision test.
