Engineers “Tread” Toward Quieter Tyres
Engineers at the University of Purdue (Indiana/USA) have developed a new technique for analysing tyre vibrations that identifies which features produce the most noise, a step toward designing quieter tyres and reducing highway noise. A mathematical model is used to identify which parts of a tyre produce the most noise. The vibrations are characterised on a graph, a visual representation that’s like a fingerprint of each tyre’s vibration pattern.
