초록

At design stage of the TRXI agricultural tractor transmission (New product of TongYang Moolsan Co., Ltd), the noise and vibration of the transmission were analyzed theoretically for the optimal design of the transmission . For this analysis, the finite element model was developed using a commercial computer software, ANSYS. The noise and vibration of the TRXI transmission housing were predicted by the modal analysis. Natural frequency of the TRXI transmission housing was ranged from 12.53Hz(1st mode ) to 30.05Hz(5th mode). The fifth mode took place at the bearing metal in the area of rear transmission housing and was very close to the gear mesh frequency (30.5Hz) of low rang gear at the low creep shifting . Based on the results , the bearing metal of the range shift housing was reenforced with the rib at design stage.
