Design and Theoretical Analysis of Acoustic Enclosure for G12V190 Type Diesel Engine

Abstract:

The existing acoustic cover is improved to reduce the noise of G12V190 type diesel engine. A panel of shutters structure is designed and simulated with SYSNOISE. The structure of acoustic enclosure is also been designed according to the structure of the diesel engine. Theoretical calculation shows that the improved insulation cover has not only a good noise reduction effect, but also has been greatly improved in terms of cooling ventilation, the field test results also shows that this section of acoustic enclosure can reduce the noise about 10dB.
