Body strength analysis of tesla

On January 2, 2023, a thrilling accident occurred in Northern California on the west coast of the United States. A Tesla sedan accidentally fell from a cliff over 76 meters high while driving, causing serious damage to the body. Fortunately, all four passengers in the car were unharmed. At first, rescue personnel expected that the passenger's chances of survival were slim, but after discovering a hand moving in the car window, they launched a rescue operation for several hours. In the end, all four passengers were rescued with only minor injuries. The police revealed that the accident was driven by a 42 year old father named Patel, who is accused of attempted murder and child abuse and is suspected of intentionally driving his car off a cliff.

In fact, the 1300 megapascal hot formed steel used in Tesla's cage body and the 1700 megapascal martensitic steel used in the bottom crossbeam mentioned by the blogger are typical applications of high-strength steel. Indeed, in modern car design, in order to ensure collision safety, some high-strength steel or other alloy materials are selectively used in the body structure.

Tesla does indeed use high-strength steel to enhance the rigidity of its vehicle body. However, this practice is not uncommon in the automotive industry. In fact, not only Tesla, but many car brands choose to use 1300 megapascal hot formed steel to strengthen the body structure. However, the highlight of Tesla Model Y's body structure lies not only in the strength of the steel, but also in the integrated die-casting process used. This process not only significantly improves the strength of the vehicle body, but also effectively reduces the weight of the vehicle. The integrated die-casting technology can make Tesla's new cars look like toy cars. ”Tesla CEO Musk once described the integrated die-casting process as follows. Tesla is the pioneer of die-casting car bodies and a pioneer and leader in integrated die-casting in the automotive industry. The entire rear body of the Model Y was first used, and the aluminum was hydraulically injected into a 6000T die-casting machine, including the anti-collision steel beam, to achieve integrated die-casting molding, significantly reducing the number of cast parts.

In short, Tesla does have its own leading advantage in the field of vehicle safety design, which is also the secret behind its ability to save passengers in many serious accidents. Wishing Elon Musk and his team to continue bringing new surprises to the automotive world!
