Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a side collision test vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a side collision test vehicle that exhibits collision behavior similar to that of a finished car and applicable to multiple vehicles.

Collision testing is essential to ensure and ensure the safety and reliability of vehicles and their components. Despite the improvement of simulation technology, it can be said that it is a feature of the vehicle field that makes safety the top priority.

The vehicle crash test proceeds in such a way that the test vehicle collides against a barrier or collides with a vehicle.

For example, a test vehicle loaded with a human body model or a sensor attached to a structure is collided with a fixture to evaluate passenger safety or component reliability, or conversely, a vehicle is collided with a test vehicle to obtain necessary data.

Although the actual vehicle is used as the test vehicle, it is not possible to perform the collision test by using the actual vehicle in all of the various vehicle parts development processes. Therefore, the collision test is carried out using the vehicle equipped with the structure simulating the vehicle.

For example, a frontal crash test may be used as a test vehicle. And a front side member and a bumper beam are mounted on the front side using a jig. However, these bogies are limited to collision testing of some parts.

On the other hand, in the conventional side collision test, the bogie is used as a moving deformable barrier, but it is hardly used as a test vehicle. If you use a jig, body in white (BIW) itself is mounted on the bogie and side impact tests were performed.

Patent Publication No. 2004-0011925 (Feb.

The present invention is based on the results of research carried out under the support of the "Agency for the Support of the Regional Economic Authority of the Republic of Korea" by the Ministry of Commerce, Industry and Energy and the Korea Industrial Technology Development Agency.

In order to guarantee passenger safety in various ways, it is necessary to perform collision tests in an environment similar to a real vehicle. However, using a finished vehicle for side collision tests during design and development is a burden, especially for component developers.

If BIW is used instead of a finished car, it will be less costly than using a finished car, but there is a problem that the actual collision behavior is significantly different from the actual vehicle.

As the deformable structure mounted on the bogie approaches the actual vehicle, the cost burden increases, and if the cost burden is considered, the collision data close to the actual vehicle can not be obtained. It is required to develop a more economical test vehicle showing collision behavior close to that of the finished vehicle.

The present invention is based on the above consideration, and aims at providing a new side impact test vehicle capable of realizing a behavior similar to a side impact of a finished vehicle.

On the other hand, the side impact test is not performed only once. Because the development part can be applied to several models, it is necessary to carry out the collision test multiple times and several models in order to check the applicability and reflect it back into the design. It would be nice if there was a test vehicle that is repeatable and applicable to many models.

Accordingly, the present invention provides a side collision test vehicle which can be repeatedly used and applied to a multi-vehicle crash test.

In order to accomplish the above object, a side impact test vehicle according to the present invention comprises: a truck having front and rear wheels; A side impact test object mounted on a truck, each truck including a front and a rear frame configured to load a heavy object.

According to an embodiment, the wheel is a passive wheel axially coupled to the bogie and is equipped with a brake system.

In addition, according to the embodiment, the axial distance between the wheel and the bogie can be adjusted.

In addition, according to the embodiment, the position of the wheel fixed to the truck can be adjusted in the front, back, or up and down directions.

Further, according to the embodiment, the bogie includes a mounting plate for mounting a wheel, which is mounted at a position corresponding to the wheel and has a plurality of fastening holes; And a connector having a base on which a fixing hole is formed so as to be fixed to the mounting plate by being fixed to the mounting plate, and a spacing member extending in the wheel direction from the base and having an axle of the wheel engaged.

Further, according to the embodiment, a plurality of mounting plates are arranged side by side between the vehicle and the wheel, and are coupled to each other by a fastening member.

According to an embodiment of the present invention, a support frame for supporting the body in the width direction is provided at one side in the width direction of the vehicle, and the support frame includes an upper cross member connected to the cross member of the floor panel, And a cross member. A side frame and a door to be tested are provided on the other side in the width direction of the vehicle.

According to an embodiment of the present invention, the roof panel and the loop cross member have a structure cut in the longitudinal direction in an intact form, and the upper cross member of the support frame is welded to the cut loop cross member. According to this, the collision support structure in the loop is almost similar to the actual vehicle, and after the collision test is completed, the support frame can be recycled.

Further, according to the embodiment, the bogie further includes a front frame and a rear frame each configured to be able to load a heavy object, and the body does not have a front and a rear frame. Several types of vehicles can be simulated by appropriately adjusting the weight of the trucks mounted on the front and rear frames of the truck.

The front frame is used to simulate the weight due to the power train or the like of the engine room and the rear frame is used to simulate the weight due to the battery mounted on the rear bottom of the electric vehicle. You will be able to load less.

According to the embodiment, the wheel is a passive wheel axially coupled to the truck, and the brake system is built. It is possible to obtain a collision test result closer to the impact behavior of the actual vehicle by operating the brake in the side collision by the vehicle.

In addition, according to the embodiment, the axial distance between the wheel and the bogie can be adjusted. According to this, a side impact test can be performed by simulating a variety of different types of vehicles.

According to an embodiment of the present invention, the bogie includes a mounting plate mounted at a position corresponding to the wheel and having a plurality of fastening holes formed therein; And a connector having a base on which a fixing hole is formed so as to be able to be fixed by a coupling member to overlap with the mounting plate, and a spacing member extending in a wheel direction from the base and having an axle of the wheel being engaged.

The side impact test vehicle according to the present invention as described above can realize a behavior similar to that of a side collision of an actual vehicle, thereby enabling the design and development of more reliable vehicle parts.

Further, according to the side impact test vehicle according to the present invention, after the crash test, the support frames and bogies other than the body can be repeatedly used again, which is economical.

Also, according to the side collision test vehicle according to the present invention, it is possible to perform collision tests in which a plurality of models are simulated by changing the weight, adjusting the balance, or adjusting the height of the lap, the car, or the body. Therefore, there is no need to perform a collision test on the actual vehicle for each vehicle type, and it is economical.
