Tesla China shares video on prioritizing security at Tesla
Tesla China shared a new video on its YouTube channel that highlights the importance placed on safety for which Tesla is well known. The video was accompanied by a clip of CEO Elon Musk explaining how important it is to put safety first.
âAt Tesla, we really believe safety should come first. We care about you. we want you to be safe. We want your friends and family to be safe. It’s primordial.
The video, which was presented in Chinese with English subtitles, was titled “Tesla Giga Safety Principle Part 1”. He shared snippets from crash tests while explaining why safety is Tesla’s top priority. Translated, the presenter said:
âSafety has always been Tesla’s top design priority. And the crash test is an important approach to get the safety parameters of a car. After countless research and development efforts, a new car faces its final evaluation – the crash test. Tesla has received a five-star rating, the highest rating in the industry worldwide by various New Car Appraisal Programs (NCAPs) and tests from insurance institutes such as the Highway Insurance Institutes. Safety (IIHS).
The narrator also explained that the vehicle has to go through all types of tests to fully assess how safe it is. These tests include simulations of various types of collisions and assessment of damage to test dummies as well as the degree of absorption and deformation of the car’s structure and the performance of its restraint system.
In the video, Tesla provides insight into how Tesla protects its drivers and occupants in different crash scenarios.
âIn the event of a collision, the strong and flexible structure and materials can effectively ensure the safety of the user. “To be strong” means to withstand huge impacts, and to be “flexible” means to deflect and dissipate the force of impact. “
The narrator shared details of how Tesla builds his structure. Tesla uses a mixture of steel and aluminum. He explained that the ratio of ultra-strength and high-strength steel used is more than 60% of the car, and it can minimize the deformation of the car in a crash. In addition to this, Tesla has a specially designed crumple zone which can maximize the absorption of a large force of the impact exerted during a crash, ensuring the safety of its passengers.
A Crash Box designed to save lives
He pointed out that among frontal impact tests, small overlap collisions require the highest safety standards and pose the most severe test for structural design and materials. One of the main advantages of Tesla vehicles is that they do not have motors. This allows the crumple zone in the front of the car cabin to absorb more force while simultaneously maintaining more crumple structures.
Another engineer pointed out other details using the front cabin structure of a body in white. He pointed to a box and noted that it was a long crash box. As the camera zoomed in on the box itself, he explained:
âThe whole aluminum crash box has a reinforced square cross section. In a collision, this piece of the crash box will transform into a wave-shaped structure.
The narrator added that the energy that is not completely absorbed by the crash box will be transmitted and dispersed to other parts of the car.
âThe first route is through the beam at the top and up to the A-pillar, then the other is from our spar to the base and out to the door frame area. There is a triangular support structure in the frontal area. This triangular support structure can effectively prevent the pedals from collapsing into the legroom in the event of a collision.
Another engineer shared information about the red front spar components and their design. They are made from super high strength thermal forming steel.
“In a head-on collision, our front cabin can withstand the thermal impact as much as possible.”
For side impact tests, these include scenarios where the car collides with a pole on the side, which the narrator pointed out is one of the most difficult tests to pass.
“This requires the side structure of the car to absorb and disperse the collision energy as much as possible.”
Tesla China engineers have shared more detailed details on how they design the vehicles to be as safe as possible. A key part of designing safety is to design it intentionally so that the doors can be opened after a collision.
They also explain how they design the vehicle to protect the battery under the floor and dive into a special technique called laser penetration welding to secure the 1700 MPa grade martensite steel.
