Description

Collision test device of vehicle

The present invention relates to a vehicle collision test apparatus, and more particularly, the barrier unit is installed to be rotated in a clockwise and counterclockwise direction for various collision tests of a vehicle, thereby minimizing vehicle collision test time and performing accurate tests. In addition, the present invention relates to an automobile crash test apparatus that can reduce the cost of an automobile crash test by minimizing installation space and facilitate the experimenter's convenience.

In general, when evaluating a vehicle, safety as well as its power performance becomes an important factor. Accordingly, each automobile manufacturer and a component supplier are conducting a lot of research and experiments to increase the safety of the automobile.

As a result, automakers and parts suppliers first carry out various safety tests to check the safety of developed cars, parts, or improved parts when developing a new car or part, or improving parts. The completeness is checked according to whether or not

The safety of a vehicle is directly related to human life and is the most influential factor in the completeness of the vehicle. In most countries of the world, the most stringent standards are applied to the safety of such vehicles.

These safety tests include seat back safety tests, endurance tests for test dummy, air bag operation test, door lock deformability test, bumper crash test, etc. These tests can be performed in the actual vehicle body to be tested as close to actual vehicle conditions as possible. The test is carried out with a slat-type impact tester, with all components mounted on it.

In addition, in the production of automobiles in general, the performance, durability, and safety of the vehicle is evaluated, and the evaluation results are reflected in the vehicle design, and the automobile development is made. As a result, various crash tests on the test vehicle (bogie) are carried out, and these crash tests require a lot of time, personnel, and budget.

These vehicle crash tests include frontal crash, offset crash (left and right), slope crash (left and right), and pole crash tests by protrusions. In each of these collision tests, collision tests with the test vehicle (bogie) are carried out while changing the collision surface of the barrier.

Conventional vehicle crash test apparatus has one collision surface, and the collision surface change for performing the above-mentioned various other vehicle collision test was manually adjusted the position or angle of the barrier on the fixed wall using a forklift as a heavy material. As such, the movement or adjustment of the barrier using a forklift truck requires a lot of time and personnel, which leads to an increase in the cost of a vehicle crash test, a high risk of a safety accident during the movement or adjustment of a heavy load, and an inconvenience for an experimenter. There was this.

In addition, the conventional vehicle crash test apparatus has increased installation space to store a variety of barriers for a variety of crash tests, the installation cost is increased, the maintenance cost of such a crash test device increases, and finally the production cost of the automobile crash test apparatus Increasingly, SMEs could not introduce them, which hindered balanced industrial development.

In addition, the conventional vehicle crash test apparatus takes a lot of time and money for the crash test because the collision or collision of each collision plane is not automatically carried out for the collision test of the vehicle even when the vehicle has two collision faces. There was a problem that the accurate adjustment is not made, the reliability and accuracy of the automobile crash test is reduced, and the stability and performance of the vehicle is finally reduced.

In addition, the conventional vehicle crash test apparatus does not secure the rigidity or rigidity of the barrier even when the barrier is partially moved for various collision tests, and thus the maintenance cost increases due to damage or damage of the barrier caused by the collision test, and eventually the automobile crash. There was a problem that the test cost increases.
