I believe that fans who have watched "Flying Life" are impressed by the picture, that is, a racing car rolling down from the mountain of Bayanbrook. In fact, all the inspiration for the movie comes from the real world.
This real event was taken from the Portuguese sub-station of the 2009 WRC (World Rally Championship). The Finnish driver Tevala, who was playing for the Ford team at the time, made a mistake in the race and rolled off the cliff. It is worth mentioning that the driver Tevala who experienced a moment of shock was not harmed, and this picture has become a classic of WRC's wonderful highlights over the years.
And CTCC also has such a "visual impact". For example, at the Shanghai station in 2017, Jin Xin of the Zongheng team also had a similar rollover accident. Fortunately, Jin Xin's body was unscathed.
This configuration that plays a protective role is the "roll cage" we often hear.
Roll cage is a detachable steel pipe assembly, which is connected or welded according to the inner contour of the car to enhance the strength and distortion resistance of the car body, and protect the safety of the crew in the cockpit in an accident.
As we all know, in all kinds of car races, the roll cage will be the standard configuration, and the Auto Federation or the race organizer will have strict standards for the use of the car roll cage. Motorsports has always been a cause to promote the improvement of automobile safety factor. In order to avoid the serious consequences of a rollover accident, the car has a basic safety modification configuration.
Whether it is a track race, a rally race, a cross-country race, or a drift race, the speed of the car is much higher than our daily driving speed. In addition, there are often unexpected factors in the race. The higher body strength of the original car to deal with these unexpected situations, in order to better protect the life safety of the driver. Therefore, the car must have this configuration and pass the car inspection before it can drive on the track.
safety iron cage shows miraculous effects
We can see from the name and structure of the roll cage,The roll cage is actually a metal tube cage placed inside the car body.
In the event of a vehicle accident, in addition to the original body to withstand the impact, the roll cage can also withstand part of the impact, and its strength and impact are many times higher than the body. With this high-strength "iron cage" protective body, the car can maintain the passenger compartment roughly in its original outline when the car experiences a collision or rollover to protect the safety of the driver.
rigorous standards to create an "immortal" golden body
Since it is designed for extreme accidents such as collisions and rollovers, the roll cage must naturally use human skills while meeting strict standards. Taking the CTCC China Auto Field Professional League Super Cup racing car as an example, the geometric structure and pipe diameter of all the rolling cages of the racing car are uniform and comply with FIA Article 253.
Participants must use specific materials and sizes of pipes in accordance with the CAD (Computer Aided Design) drawings provided by the official frame supplier. All roll cage pipes included in the drawings cannot be deleted.
In addition, in order to ensure the strength of the racing suspension hard points and facilitate the installation of the steering column, the number of pipes in the roll cage can be increased for some models. The additional pipes must be pipes with a diameter of 30 mm and a wall thickness of 1.5 mm. .
With high-standard roll cage protection, the driver can be injured as little as possible in the accident. Racing is a dangerous issue, but thanks to the efforts of countless racing people, the safety of racing continues to improve. While protecting the safety of drivers, it also promotes the development of safety technology for civilian vehicles. And this is one of the meanings of motorsport.
