Abstract:
      The simulation and experimental research of the tire near-field noise based on circular sound source was introduced.The finite element simulation calculations of the tire noise sound pressure level were respectively carried out by using the circular sound source model and the equivalent point sound source model，and the tire noise sound pressure level test was conducted.The results showed that，the error between the simulation valve of the tire noise total sound pressure level calculated by circular sound source model and the test value was －1.3 dB（A），and the error between the simulation valve of the tire noise total sound pressure level calculated by the equivalent point sound source model and the test value was ＋2.9 dB（A）.The simulation results of the tire noise by the circular sound source model were more reliable，and the finite element simulation of the circular sound source could provide guidance for the low-noise tire design.
