Versailles Long Test 52: Versailles Collides 5 Stars, Do You Really Understand Crash Test?

I believe that even if you have not seen the car crash test on the spot, you have seen pictures or videos of the car crash test. So how do you tell if a vehicle is safe? Except for the airbags that are all popped out and the A column is not curved, can you not see anything? So in this article, we take Versailles' crash test at C-NCAP as an example. Let's take a closer look at the C-NCAP crash test.

First of all, we need to understand what C-NCAP crash tests are. In total there are 6 projects. The first is a frontal 100% rigid crash test. The second is a side impact test. The third is a frontal 40% bias crash test. The fourth is a seat whipping test. The fifth is a pedestrian crash test. The sixth is an active safety test.

Secondly, in the crash test, there is no gasoline in the vehicle, and some water is usually put in the fuel tank. Because the crash test vehicle will have a slide underneath, the vehicle will be brought to a certain speed collision, rather than driving itself to collide. At the same time, the vehicle is also colliding in a state of shutdown, and the vehicle does not ignite.

Below we will explain the 6 projects just mentioned one by one.

[1] 100% collision front

The first is a frontal 100% rigid crash test. The requirements for the test are carried out at a speed of 50 km /h. At this time, the main test is the front bumper of the vehicle, the collapse of the engine compartment, and the rigidity of the A-pillar, and also tests whether the airbag on the front of the main co-pilot can be opened normally.

This is something we can observe with the naked eye, and there are dummies in the car, front and rear rows. There are even dummies that simulate children, and they have sensors on their bodies to see how hard they are in the car and whether the airbags protect the passengers.

[2] Side impact test

The side crash test is the vehicle under test that is stationary, and another crash vehicle is used to impact the test vehicle at a speed of 50 kilometers per hour. The main test here is the strength of the vehicle's B-pillar, including the strength of the front and rear doors, and whether the front and rear side air curtains can be opened normally.

Of course, after the side collision, the door must be deformed, so in the case of deformation, can the door still open normally? The fuel tank will not break. There is also the status of the dummies in the car are the evaluation criteria.

[3] 40% bias collision on the front

The frontal 40% bias collision is a test vehicle at a speed of 64 kilometers per hour, and 40% of the contact area of the front of the vehicle collides with the obstacle. That's what we call a small-angle crash test. It's like the relationship between stress and stress that we learned in junior high school. If the contact area is large, the pressure is small. However, if the contact area is small, the pressure is strong.

This crash test actually tested the bumper, the collapse of the starting chamber, and the strength of the A-pillar. Especially if the bumper is not long enough and the protection is not in place, then it is a loss in 40% of the bias collision.

[4] Seat whipping test

The whipping test of the seat is a separate test for the seat, and the seat is disassembled for a separate test. The test consists of both static and dynamic parts. Static is the height of the headrest and the gap behind the head. Dynamics is the process of simulating a collision by testing with a slide rail. Then look at the state of the dummy, especially the force on the neck. Because in actual crash tests, our necks are particularly vulnerable to damage due to inertia.

[5] Pedestrian collision test

Pedestrian crash testing programs basically don't have much to do with drivers and passengers. Because it tests mainly pedestrian safety. Because today's car safety must not only consider themselves, but also consider the pedestrians on the road. How to reduce the harm of pedestrians is also important. We say that pedestrians are also divided into various situations, such as pedestrians who walk taller and pedestrians who ride bicycles are shorter. So this test is mainly to simulate their different degrees of damage to their calves, thighs, and heads after a collision with a vehicle.

[6] Active security testing

Active safety testing has only been added in recent years, because vehicles are becoming more and more intelligent, including AEB automatic emergency braking system, lane keeping system, lane departure warning system, blind spot monitoring system, have become more and more popular, and even by many manufacturers to promote. Therefore, C-NCAP also increases the weight of active safety testing.

Active safety test is to see if the vehicle can achieve active braking when encountering obstacles or pedestrians in front, if there is no brake to cause harm to pedestrians, then the score is low.

Of course, the above is a very, very simple interpretation of my C-NCAP test standard. The true C-NCAP crash test is very rigorous and takes 3 days to complete in total. Various sensors inside and outside the vehicle will form a complete report of the test data. The 5-star safety and 4-star security we see are actually very simple. Because 5-star safety is the score evaluation of all these items that I just said. After all, some cars have advantages in individual projects, and some cars have disadvantages in individual projects. But the average score is very high, then it is all 5 stars.

Finally, let's talk about the Versailles crash test results, the results are very good. Because I've said before, the current C-NCAP crash test, it's an open-book exam. Crash test standards have long been made public, so various automakers can actually make targeted safety considerations in the stage of product development.

Versailles C5 X C-NCAP Whether it's a frontal side crash test or a frontal 40% small angle crash test. It can be seen that the appearance integrity of the occupant cabin after the collision is good, A pillar, B pillar, threshold, front and rear anti-collision beam, and door anti-collision beam reasonable deformation and energy absorption; front airbags, side air curtains, side air bags and seat belts and other restraint systems act in a timely manner, effectively protecting the occupants' head, chest and pelvis and other parts; the front windshield, door glass and large skylight do not appear significantly broken, reducing the risk of the occupant body extending the body; after the collision, the door is unlocked normally, to meet the rescue and escape needs after the accident, and the brake can be stopped in time in the active safety test. Excellent overall performance.
