Excessive vibrations - excessive to the point of injury - have been prominent in the news recently, but researchers have developed an algorithm that could help machines avoid getting trapped in resonant motion. Using a combination of computer simulations and experiments, they found that by carefully increasing and decreasing the speed of a rotor, they could nudge it past its resonant frequency. The rotor doesn't get stuck in resonance like the faulty washing machine. The researchers describe their work in this week's Chaos.
