| Abstract: | Based on the identification of the noise source of the Dongfanghong-150 Tractor's trans-mission system,the complex model analysis of its transmission case has been carried out.Containing and supporting the transmission gears,shafts and bearings,the transmission caseis an important component,through which mechanical noise spreads outside. Model testingproved that the vibration amplitudes of the third and ninth modes of its side walls are largerand consistent with the frequencies of the radiant noise,So the noise level can be lowered byimproving the construction design of the side walls of the transmission case. |
