The main objectives of the Silent Safe Road Traffic project are:
- Knowledge: Development of fundamental insights into the tire-road surface interactions "grip" and "noise";
- Valorisation: Development of innovative silent and safe tire-road combinations;
- Social interest: Less noise, safer road traffic and consolidating / growth of employment.
Within this project, an in-depth and systematic investigation will be conducted into two aspects of the tire-road surface interaction; grip and noise. To this end, the following activities will be performed:
Equipment
- 3D macro roughness road + water. Development, design and construction of a measuring instrument for 3D scanning of asphalt on mm scale;
- 3D macro roughness road. Development, design and construction of a measuring instrument for 3D scanning of asphalt on mm scale;
- 3D micro roughness. Development, design and construction of a measuring instrument for 3D scanning of asphalt on a µm scale;
- Contact temperature. Development, design and construction of a 2D temperature sensor (using existing infrared technology) to simultaneously measure the temperature development in time and position of the road surface and tire at high speed (80 ~ 100 km / h);
- Integration trailer of the above measuring equipment.
Grip
- Set up research test methods indoor at lab level of Surface-Force-Apparatus (SFA) and LAT100 (rubber test wheel) and outdoor at tire-road surface level of a measuring trailer.
- Investigate grip on SFA, LAT100 and measuring trailer on different rubbers / road surfaces wet and dry.
- Research and validation of the friction model on the grip of dry (and possibly wet) tire-road surface contact that describes the above measurement results.
- Calculation of a safe rubber-road surface combination.
Noise
- Research into dynamic tire-road surface contact
- Research and validation of the detailed modelling of tire-road surface contact in the current complete physical tire-road surface noise model.
- Calculation of the quiet tire-road surface combination.
Prototypes
- Design and production of quiet AND safe tire-road surface combinations.
- Demonstration of silent AND safe tire-road surface combinations.
