Hub of the problem

摘要

In october researchers at Cambridge University will begin a project that aims to develop improved techniques for modelling, and ultimately reducing, vehicle cabin noise. One of the chief causes of this is vibrations passing from the tyres to the suspension and then into the vehicle's structure. Traditionally, engineers have tried to reduce the vibrations by improving tyre or suspension design. But Will Graham, who is leading the project at Cambridge's engineering department, feels that these efforts have repeatedly overlooked the high-frequency vibrations generated through the wheel hubs. He believes that addressing this problem is the key to reducing cabin noise.
