In recent years, with the emergence of various models, SUV has gradually become one of the mainstream models, and Volvo XC60 (Configuration | Inquiry), as the leader of medium-sized SUV, has excellent performance of face value and intrinsic safety performance, strong strength, very eye-catching, and has won the attention and favor of many successful fashion people. This makes people expect what surprises Volvo XC60 will bring us.
A few days ago, Volvo XC60 conducted a very exciting safety performance test. Seven XC60 cars were used to test the safety of Volvo XC60, and the performance in the test was convincing. Through the superposition of vehicles, the compression value of the carrying vehicle has changed, from the initial 1625mm to 1600mm, and the deformation of the first vehicle is relatively large at the initial stage, and then tends to be gentle. After 24 hours, six cars on the roof were removed, and the height of the car body rebounded by 15mm, that is to say, after being pressed by six cars for 24 hours, the whole car body was only deformed by10 mm. In the whole car stacking experiment, the Volvo XC60 car body structure was intact and the deformation was very small, and it was really a "tank on the road".
In order to have a more comprehensive understanding of XC60, Zhihu's official account Zhihu Automobile recently dismantled it and answered our questions from a professional perspective. The achievement of Volvo XC60 is inseparable from its cage body design and boron steel materials used in the body.
The overall structure of Volvo XC60 cage, as seen from the cross frame, has five ring structures, and the cross-sectional area of these ring structures is relatively large. At the same time, there are five longitudinal structures on the floor of the carriage, so that the whole cage can protect the safety of the carriage well, because the cage knows how to unload the force, and the collision force is transmitted and decomposed to the whole body through the cage structure to avoid structural damage caused by excessive local stress. At the same time, it can absorb the energy of collision through the whole body.
Excellent body structure design is important, but without the use of excellent materials, all this is empty talk. Volvo XC60 adopts hot-formed boron steel, and the utilization rate of boron steel in the whole vehicle is as high as 34%, while the content of boron steel in general vehicles is only 10%. At the same time, Volvo XC60' s thermoformed boron steel is used for A/B/C columns, sill rails, front floor rails, central passage and rear floor rails. At present, most manufacturers only use hot-formed boron steel in A/B column, but XC60 also uses boron steel in C column, which is very rare. For example, this stacking test simulates the protective ability provided by the cage when the vehicle rolls, so the focus is on the dispersion of the roof pressure by the body structure, especially A.
In the medium-sized SUV market, Volvo XC60 has not lost its sense of luxury and grade, but at the same time, it shows a level that other SUVs can't reach in terms of safety, and its safety performance is also very strong, which is worth choosing.
