“Simulations offer a relatively deep insight into what happens during a crash,” explains Tomáš Kubr. “When I run a crash test with a real car, all I can do subsequently is evaluate the results and data from pre-installed sensors. We can’t install sensors everywhere, though. What’s more, if, after evaluating a particular crash test, I decide to test some other parameters, change the car’s speed, and so on, then I would have to destroy another car. With supercomputing, I just change the input data and repeat the test.”
The results speak for themselves. For example, 99% of the crash tests performed in the development of the KODIAQ were done on the computer and only 1% with real cars. Even so, real-car tests are still very important, because they are ideal for checking design solutions and for developing the virtual-test methods further.
