[YesAuto Technology] How much change can happen in two years? For a person, perhaps from a dashing youth to a bloated uncle, or from an ignorant girl to a gentle mother. For a car company, it can take only two years to go from a car with a two-star score in the C-NCAP crash test to a SUV with a five-star rating. While enriching the product line, we also fought a beautiful turnaround in C-NCAP. This kind of thing came from the hands of Tianjin FAW. From the Weizhi V5 in 2013 to the Junpai D60 today, Tianjin FAW used two years of Time has brought the safety of new models to a new level.
In the first batch of C-NCAP crash tests in 2015, Tianjin FAW Junpai D60 received a five-star rating of 59.6. The “H-Body” cage body structure of Junpai D60 played an important role. When a vehicle is hit by a frontal impact, the huge energy from the collision needs to be absorbed and dispersed. Therefore, the front of the vehicle must assume the role of energy absorption. At the same time, the energy that cannot be fully absorbed must be dispersed and transferred to other structures of the body to avoid energy concentration. A little bit causes greater structural damage, which is also the mainstream idea of the current body structure design.
From the theoretical analysis, it can be seen that the design purpose of Junpai D60's body structure is very clear: the front of the vehicle absorbs collision energy, while using the body structure to transfer and disperse the energy that cannot be absorbed, so as to maximize the integrity of the passenger compartment structure. , Provide enough safety space for the personnel in the car, of course, this is also the most effective design concept recognized at present. The way to verify whether the body structure can complete the design goal is practice, let us look at the performance of Junpai D60 in the C-NCAP crash test.
-Frontal 100% rigid barrier collision test
Score: 16.79 points (93.28%)
The frontal 100% rigid barrier collision test mainly examines the energy absorption effect of the front structure of the vehicle and the effect of the restraint system in the vehicle. The front structure of the Junpai D60 can better absorb the energy of the impact, ensuring the integrity of the passenger compartment, and the restraint system has also played its due role.
-Frontal 40% deformable barrier impact test
Score 17.3 points (96.11%)
Due to the higher collision speed, smaller collision area, and more concentrated energy, in the frontal 40% deformable barrier collision test, the body structure not only needs to absorb the collision energy, but also needs to transfer and disperse the energy through a reasonable design.
-Side impact test
Score: 18 points (100%)
In a side collision, due to the insufficient energy-absorbing structure on the side of the vehicle and the occupants in the vehicle are close to the impact position, the rigidity of the body structure is very important. In addition, the effective transmission of energy also plays a key role in the result of the collision. The Junpai D60 body can transmit and disperse energy to the other side of the body through the roof and floor beams. At the same time, the H-shaped structure at the impact position also effectively ensures the integrity of the passenger compartment.
Score: 4 points (100%)
The whiplash test mainly investigates whether the vehicle's seat can give the occupant's neck adequate protection when it is hit from the rear. Although this test is not to investigate the structural design of the car body, it is also an indispensable content in the passive safety indicators of the vehicle.
Score: 3.5 points (4 points total)
The Junpai D60 sent for testing is equipped with a driver's seat belt reminder device (1 point); ISOFIX device (0.5 point); ESC (1 point) and side airbags and air curtains (1 point). Among them, the vehicle seat belt is provided by Sweden Autoliv; the ESC is provided by the German mainland; the airbag and side air curtain are from the US TRW.
to sum up:
After the two-star “failure” of Weizhi V5 at C-NCAP two years ago, Tianjin FAW has made major adjustments and changes in product safety research and development. In the end, the outstanding performance of Junpai D60 has helped Tianjin FAW. A beautiful “turning over”. In addition to passing the C-NCAP crash test with high scores, the Junpai D60 also uses Toyota Boshoku's environmentally friendly interior components to ensure the “safety” of the driver's and occupants' breathing. In addition, Tianjin FAW is also actively cooperating with world-renowned component suppliers such as Bosch, Denso and Aisin to ensure the quality of vehicle driving. It is believed that these efforts will enable Junpai D60 to further enhance its own strength and obtain more consumption. Favored by the audience.
