Abstract:
      Through the orthogonal test design，the optimal belt structure parameters combination for low tire vibration noise was obtained，and the noise reduction mechanism of tire was analyzed.The results showed that the order of belt structure parameter affecting tire vibration noise was as follows：cord angle of 2# belt，cord angle of 3# belt，width of 2# belt，width of 3# belt.After optimization，the high-order natural frequency of tire increased，and the radial vibration was less easily excited；the peak values of acceleration at tread and sidewall measuring point decreased，the influence on the acceleration of tire tread and sidewall measuring point was mainly reflected in mid-frequency and high-frequency，respectively；the excitation force power spectral density fluctuations and peak values decreased significantly，especially at 440 Hz sensitive frequency significantly reduced.
