Technology sought for development of Tyre-road Noise Prediction and Improvement (12 TR 99PB 3NZ9)
Popis:
A Turkish engineering SME specialized in NVH (noise, vibration, and harshness) development of different type of vessels is looking for partners in order to develop models to predict tyre/road noise. The technology sought can be already in the market or can be developed jointly with partners under EUREKA or Eurostars projects, as well as under FP7.
Since the increase of the interest in development electric powered vehicles, most of the noise sources have already been removed from the land vehicles which generate considerable exterior noise (cooling fan unless a water cooled battery is used, exhaust systems, intake systems, engines etc.). Therefore, tyre/road noise became the dominating exterior noise source. However, prediction of the tyre/road noise by analytical or CAE models have been limited to some research centres as the problem is complex especially due to the combination of a rotating system with different tyre track designs. However, tyre exterior noise limits are already determined and tyre manufacturers need some tools (CAE, test or hybrid based) to predict the radiated noise levels before building a prototype. Therefore, the Turkish company is willing to cooperate with partners experienced in tyre manufacturing to develop a method for tyre-road noise generated. These projects may include building acoustic test chambers with different roughness pavement surfaces and developing software to help estimate the radiated noise depending on tyre texture. Eventually, a low noise tyre may be developed.
Technical Specifications / Specific technical requirements:
Improvement of tyre noise should not degrade principal duties such as handling, rolling resistance etc. Tyre/road interaction noise depends on various factors which have not been investigated in detail up to now (only limited resources are available). Some mechanisms are being proposed to be the main sources, such as cavity resonance, tyre texture, road roughness etc. Considering that designing the tyre texture with misaligned texture has mitigated some characteristic noises already. But the noises generated due to the tyre/road interaction have not been fully simulated due to the complexity. Therefore, a hybrid methodology may be required to estimate and decrease the level of complexity. Eventually a silent tyre may need to be developed.
Degree of development:
Patents/Rights:
Requested Cooperation: Engineering, Technical consultancy, Joint further development, Testing of new applications, Adaptation to specific needs
- Type of partner sought:
Industry, Tesearch Institute, Technical Centre.
- Specific area of activity of the partner:
Preferably the partner should be a tyre manufacturer or working in this area.
- Task to be performed by the partner sought:
Involve with the Turkish company in the development of a methodology and silent tyres and manufacture alternative design proposals so that iterations can be conducted.
