| Abstract: |
| Taking 215/75R17.5 truck and bus radial tire as the object，using Abaqus/Explicit to simulate the rolling process of tire on the drum and analyze its vibration characteristics.In order to verify the accuracy of the finite element analysis method，Doppler laser vibrometer was used to measure the vibration response of measuring points on tire sidewall in the time domain，and then Matlab corrugated medium low pass filter Firpm function was used to filter the measured time domain signal，vibration frequency response signals between 20～500 Hz were retained and Fourier transformed，compared with the simulation values of the frequency domain，they had good consistency，which proved the accuracy of the finite element analysis method for rolling tire.Based on the finite element simulation，the effects of velocity，inflation pressure and load on the tread and sidewall vibration characteristics were analyzed.The results showed that the tread vibration velocity distribution was symmetrical about tire vertex，the amplitude of vibration velocity close to the ground was maximum，and the vibration velocity of ground back end was larger than that of ground front end.With the increase of velocity and inflation pressure，the vibration velocity of tread and sidewall increased，and the load had little effect on the vibration velocity of tread and sidewall. |
