                 Abstract: In view of the lack of noise prediction of vibrating wheels at home and abroad, taking a vibration
                 wheel as the research object, the frequency response of the vibration wheel is analyzed based on the dynamic
                 finite element theory, and then the acoustic boundary element technique is used to simulate the radiated noise
                 of the vibration wheel. The accuracy of the simulation results is verified by experiments. Then the effects of
                 vertical vibration and circular vibration on radiation noise are compared, and a conclusion is drawn that the
                 radiation noise of vertical vibration is low. Finally, the acoustic cavity mode of the cab is simulated, which
                 is similar to the excitation frequency of the vibration wheel. By adjusting the excitation frequency, the noise
                 near the driver’s ear is reduced. The results obtained in this paper can provide a practical reference for the
                 prediction and improvement of radiated noise of vibration wheel.
