Crashing a carbon fiber physique is a complete new world in comparison with conventional metal our bodies.
In preparations for the manufacturing launch of its first-ever mannequin, Polestar is investing tens of millions of into meeting traces, manufacturing websites, and completely different evaluations. In truth, the verification prototype manufacturing of the Polestar 1 has already began and the corporate is now utilizing the primary assembled examples for crash checks.
That is the primary time Volvo and Polestar are experimenting with a carbon fiber bolstered polymer bodyand researching it in actual crash eventualities. In distinction to a normal metal physique, carbon fiber dissipates power by cracking and shattering, which requires a complete new degree of engineering. Particular consideration is given to the best way the fabric reacts to excessive forces throughout impacts.
With this new testing process, Polestar explains, the corporate needs to arrange its automobiles for the issues that aren't deliberate, equivalent to accidents. It putts the verification prototype automobiles by crash checks at completely different speeds and varied angles.
“It’s dramatic. It’s exhilarating. And it’s crucial.”
Essentially the most extreme state of affairs simulated by Polestar is a frontal collision right into a stationary barrier at 35 miles per hour (56 kilometers per hour). On this case, a lot of the power of the influence is absorbed by the automotive’s crash construction. The remainder of the power mitigates by the carbon fiber physique panels into the physique construction.
“We have been actually enthusiastic about this crash take a look at. The primary crash take a look at of Polestar 1 has been about exploring the unknown. This was an important proof level within the growth of Polestar 1; we needed to know that the concepts and calculations which have gone into constructing this automotive have been proper – they usually have been,” described the method Thomas Ingenlath, Chief Govt Officer at Polestar.
Crash checks with the brand new Polestar 1 will proceed within the subsequent weeks. The corporate is utilizing the Volvo Automobiles Security Middle in Gothenburg, Sweden, the place automobiles and different automobiles could be crash-tested in a lot of real-world simulations.
