Abstract
A method for simulating tire noise performance using a computer includes a step Sof setting, using a finite number of elements, a tire model having a tread model portion provided with a tread groove, a step Sof setting a road surface model using a finite number of elements, a step Sof carrying out a rolling simulation to roll the tire model on the road surface model at least over a groove-grounded rolling distance between which the tread groove is brought into and out of contact with the road surface model; a step Sof acquiring a surface coordinate value of the tread model portion in a time-series manner, and a step Sof setting a sound space region around the tread model portion using the surface coordinate value of the tread model portion and of carrying out an aerodynamic simulation using the sound space region.
