What is NCAP?

1. China-New Car Assessment Program (C-NCAP) is a set of collision test inspections.The evaluation standard of the collision safety performance of automobile products is higher than the national mandatory standard. The evaluation results are divided according to six stars, and the collision results are publicly released.

2. NCAP is the abbreviation of New Car Asses *** ent Program in English, that is, new car crash test. This is the best test to test the safety of cars.

3. NCAP (New Car Evaluation Program) The new car evaluation program first began in the United States. In 1978, NCAP proposed a five-star evaluation method to evaluate the performance of cars in protecting osccupants in frontal collisions.

4. NCAP is the abbreviation of New Car Assessment Program, which means new car collision test, judgmentThe result is expressed in star rating, with the highest five stars and the lowest one star. The often heard five-star collision refers to the NCAP test.

5. NCAP car crash test is a new car crash test that can test the safety of cars. The following is the test information: Collision content: It is divided into frontal and lateral collision. The frontal collision speed is 64 kilometers per hour. The side collision speed is 50 kilometers per hour.

10 cars with the safest and highest crash test rating

1. The safest suv ranking Volvo XC90 Volvo XC90 is a large imported SUV, tough The car body is very majestic. The seat support and acceleration comfort of this car are extraordinary. SafeAs Volvo's watchful skills, the Volvo XC90 still has the strength to crush competitors of the same level.

2. As a German car, the general impression of Audi is that it is crash-resistant. Coupled with its advanced safety technology, it is reasonable to rank in the top 10. Mazda, a Japanese brand of Mazda, in the 2017 IIHS collision evaluation report, many products of Mazda participated in the collision won the TSP+ award.

3. For cars with the highest safety factor, I believe that the first thing most people think of is Volvo cars. An enterprise that engraves safety in its bones, it invests a large amount of money in safety research and development every year. For Volvo cars, there has always been a stalk in the circle of car lovers, "Buy Volvo cars, use them for a lifetime, or sell them.

4. The top ten cars with the highest safety factor are as follows: Volvo is a famous safety car. This brand puts the vehicle safety factor first, followed by the configuration, which also leads to Volvo having nothing to do except safety, so it is the safest car product. Card.

5. The car with the highest rating in the safest crash test. First place: Subaru Tiger has received good and excellent ratings in all IIHS collision performance, anti-collision and mitigation tests. Subaru Tiger has won the title of Top Security Choice+ and has many popular security features.

Can the beam widening improve the deviation collision test results by 25%

The performance of the frontal 25% bias collision is good. In the test of the frontal 25% bias collision, Corolla's performance is still very good, and the performance of each small project is also excellent. This is mainly due to the good structural design of TNGA architecture. And whether it's Corolla or Camry, Lei Ling's performance is very good.

The 25% bias collision on the front side of China Insurance Research Institute imitates the collision of vehicles, walls, telephone poles, etc. on the front side of the car. According to the test standards, the car will hit a 5-meter-high rigid barrier at a speed of 64km/h and an overlap rate of 25%.

Judging from the results, the safety evaluation of in-car occupants, the safety index of pedestrians outside the vehicle, and the vehicle auxiliary safety index all received excellent evaluations of G. Among them, the bigThe area glass causes worrying about the strength of the roof. Xiaopeng G3 did not pull the crotch, and there was basically no deformation in the test.

The latest crash test results show that G was obtained in 25% of frontal collisions, and there was no obvious deformation of the A column. The side collision also got a G score.

Generally speaking, the Passat 25% bias collision performance is very good, the structural strength is intact, the airbag function is stable, and the restraint force of the seat belt is also quite good. The difference between the results before and after is so big, will it be fishy? Is China Insurance Research Institute being "publicized" again? In the author's opinion, this possibility is basically not possible.

Is car collision a mechanical test?

In mechanical experiments, the mass of the car is required to be much larger than the mass of the weight is generally when studying the law of conservation of momentum or impact experiments.

Passive safety performance has always been the focus of automobile safety research, and automobile collision testing is the main means of passive safety performance research at present. Vehicle collision tests mainly include real vehicle collision tests and pulley collision tests. The trolly collision test has the advantages of low test cost and short preparation cycle, so it is widely used.

Verifying the theorem of the kinetic energy of the cart requires the mass of the cart to be much greater than the mass of the weight. As long as the gravity of the weight is approximately equal to the tensile force of the rope, it must be much greater. What is basically not needed is to study the system (carts and weights), such as verifying the kinetic energy theorem of the system, the conservation of mechanical energy of the system, etc.

So as to judge the quality of the car. On the one hand, automobile collision testing can provide safety reference for automobile enterprises and promote benign improvement in safety; on the other hand, it is the intervention of the state, and the constraints of laws and regulations can continuously standardize industry safety standards, so as to maximize the safety of consumers.

Car seat front and rear collision test standard

1. Confirm whether the seat is invalid, whether the seat is broken and removed during and after the test, and whether the seat can maintain integrity.

2. The impact strength test bench of the car seat headrest simulates the impact process between the passenger's head and the internal parts of the vehicle (such as the seat headrest, dashboard, shade panel and internal protruding objects, etc.) in the event of a collision or a large reduction in the vehicle.

3. ● Front 40% overlap deformable barrier collision test (64km/h~65km/h) out of 18 points. Place a HybridIII 50th percentage male dummy in the front-row driver and occupant respectively to measure the injury of the front row personnel.

4. The middle position of the rear seat of many models does not have a headrest. If someone sits in the middle position of the rear row, it is recommended to install a headrest. Women are 8 to 2 times more likely to have head and neck injuries than men in vehicle collisions.Therefore, women should pay more attention to adjusting the height of the car headrest when driving.
