They include the vibrations of the tread block and carcass, tread block slip friction, carcass inner standing wave patterns and air pumping of the tread pattern. The frequency of the air pumping of the tread pattern ranges from 800 to 1200 Hz, which is the typical frequency range to which human ears are sensitive. Therefore, air pumping has a direct influence on noise. This study uses the finite element software, Abaqus, and the fluid mechanics software, FlowVision, to establish an air pumping noise model for tires. The model simulates the air pumping effects of the tire tread. The change in sound pressure is converted from the time domain to the frequency domain by fast Fourier transforms, and A-weighting modified sound pressure levels are added to calculate the spectrum and the total sound pressure level. The air pumping noise model for tires was verified experimentally and utilized to study the influence of tread pattern pitch on the air pumping noise. ? 2019 Ecological Society of India.
