Speron 2020 - Optimal tyre design for electric cars (Leisstra 3, part project 4)

Start date 01/12/2010
End date The project is closed: 31/12/2013

​The engine of electric cars is very different in sound from traditional combustion engines. In addition the forces acting between tyre and road during acceleration are substantial higher for electric cars. This demands a different tyre optimisation where at low driving speed it would be appreciable to have a somewhat noisier tyre to increase the awareness for pedestrians. At the same time the design should not increase noise at medium and high speed where tyre/road noise is very strong and dominant. 

 

The project is carried out at the Division of Applied Acoustics in the researchgroup Vibroacoustics.
