Development of Low Noise Working Machine based on CFD Technique 2002-32-1802

The demand for the noise reduction of working machines, such as construction machines, tractors, and generators, has been strongly increasing. In order to achieve noise reductions, a low noise fan was developed using the CFD (Computed Fluid Dynamics) technique. The engine enclosure was developed, not only to reduce the noise emitted from the engine efficiently, but also to improve the cooling performance. Finally, the average noise level of working machines was reduced by about 10dB(A).
