All round car designer

Chapter 133 Five Stars
As an essential part of car design, vehicle crash test is a very important safety guarantee for new cars. Any new car must pass the crash test before it goes on the market!

Among the current crash test standards, the NCAP car crash test is the most stringent. It is divided into two types: frontal and side impact. overlapping deformable barriers) collide with both, and the side impact speed is usually 50 km/h.

In addition, there are center pillar crash tests and rear crash tests.

In terms of evaluation indicators, the crash test is divided into five stars, and the higher the star, the higher the safety performance of the car.

Of course, it is not to say that vehicles that can reach the five-star crash test will not have accidents when they encounter traffic accidents. The crash test only provides a standard for safety evaluation. It can only be said that the car that has received a five-star rating in the crash test , the best protection for occupants in the event of an accident.

Zhou Fei checked carefully on the Internet. There are currently many institutions in China that can provide crash tests. Large car companies like Chunqi and Shenqi even have their own crash laboratories, but the standards for such crash tests are very low. Usually, automakers are "self-conscious". The most well-known evaluation organization is CNCAP, which is also a derivative of NCAP in China.

When CNCAP is evaluating, it will evaluate the results in accordance with stricter and more comprehensive requirements than the current domestic mandatory regulations. This test result is also the most popular promotion of major manufacturers. One of the most recognized crash test evaluations.

According to the workflow given on the Internet, Zhou Fei successfully submitted the application report on the QQ crash test, and on the third day after submission, he received a notice from CNCAP: the QQ crash test was scheduled for February The morning of the 2rd!

Since the requirements of this test are very strict, and its results will be announced on the entire network, if the star rating is not high, it will directly affect the sales of this car.

Therefore, in order to ensure a high score in the CNCAP test, many manufacturers will secretly conduct a "understanding" test when conducting this test, and make timely rectifications according to the problems exposed in the test, so that they can be in the CNCAP test. performed better in the test.

However, Zhou Fei didn't do any "foundation" tests. One reason is that Mercedes-Benz currently does not have its own crash laboratory. If it wants to conduct a thorough investigation, it has to entrust other OEMs. The procedure is a bit cumbersome.

More importantly, Zhou Fei has great confidence in the QQ car. When Chery was designing and developing this car, it strictly implemented the ISO/TS16949 quality management system, the most stringent and advanced quality assurance measure in the world. A small micro car with a high degree of safety.

Zhou Fei believes that according to CNCAP's implementation standards, the crash test results of QQ must be five-star!

Therefore, Zhou Fei didn't need to do a thorough test at all, he only needed to go through a CNCAP test directly.

Before the test started, Zhou Fei had prepared the test vehicle according to the official requirements, and arrived at the crash laboratory designated by CNCAP one day in advance.

On the second day, CNCAP started a new round of crash test in its own crash laboratory.

Wang Liyong, the engineer in charge of today's crash test, checked all the models that participated in the test today as usual. A total of six cars were arranged to participate in the test in the morning. The first five models are very familiar to Wang Liyong, and they are all old models on the market. .

When he saw the sixth model, Wang Liyong couldn't help but take a few more glances, "It turned out to be the QQ of Mercedes-Benz!"

Wang Liyong is no stranger to the QQ car, especially recently, with the release of QQ spy photos, this car has aroused heated discussions in the domestic auto industry.

Frankly speaking, Wang Liyong quite liked the design of this car, especially the displacement of this car, which won his heart even more. He is not a car enthusiast. To him, a car is just a means of transportation. The lower the fuel consumption, the better.

As for the QQ car, it can be said that it perfectly fits all Wang Liyong's fantasies about the car. It is not expensive, has low fuel consumption, and is stylish in design. Wang Liyong really can't think of any reason not to buy this car.

"If today's crash test reaches more than three stars, then I will definitely buy one to take home this year!" Wang Liyong stared at the QQ on the list and whispered.

In order to ensure the fairness of the crash test, during the test, only CNCAP staff can operate on site, and the major manufacturers participating in the test cannot enter the laboratory, and can only wait outside for notification.

The evaluation of each car takes at least half an hour, and QQ is scheduled for the last one in the morning, so Zhou Fei did not rush to CNCAP, but stayed in the hotel first, and waited until half an hour before the start. It's not too late to go.

***
After everything was ready, Wang Liyong started the evaluation of today's first car, which is the Yajia from Chunqi Benma.

This model designed by the island country Benma Company has always been one of the best-selling cars in China. In the previous crash tests, it has always received four-star and above evaluations.

Wang Liyong believes that the performance of this car today will not be too bad either.

After checking the test dummy and sensors in the car again, Wang Liyong nodded to the staff, and Yajia's crash test officially started.

The first thing to do is a frontal collision with the rigid fixed barrier with a 100% overlap rate.

After some adjustments by the staff, the test vehicle quickly rushed to the test wall ahead at the set speed.

There was only a bang, and Yajia slammed into the wall hard. At this time, the front face of the car was seriously deformed, but whether the car was seriously deformed during the collision is not the only way to judge the test results. The standard mainly depends on the degree of protection of the dummy in the car.

In a general traffic accident, the main reason for the collision of two vehicles, resulting in the casualties of the driver and passengers in the car, is that after the deformation of the C-pillar and B-pillar of the car, the space of the cockpit and the passenger compartment is squeezed, which is harmful to the occupants of the car. While causing damage, it will also increase the difficulty of rescue, causing secondary damage to these people.

Therefore, when evaluating the crash test, the standard is multi-faceted and three-dimensional, and it is necessary to comprehensively judge a variety of situations.

After the collision, Wang Liyong stepped forward immediately, while observing the damage degree of the dummy in the car, he retrieved the relevant data from the sensors in the car, and according to the judging criteria, he quickly concluded that the dummy of Yajia was The results of a frontal collision with a 100% overlap rate of a rigid fixed barrier between vehicles:
15 points for the protection of the front row occupants, 1 point for the protection of the rear row occupants, a total of 16 points!
In the score of CNCAP, the scores of the three collisions are all 18 points, and the last one is 4 points for the whipping test, with a full score of 62 points. The 16 points obtained by Yajia are already at the upper-middle level.

After finishing the first test, Wang Liyong conducted the remaining tests on this car. In the end, the comprehensive score of Yajia was 58 points. Would get 52 stars!

Yajia has maintained its high standards as always!
