<p>The noise performance of a tire is estimated with satisfactory accuracy. A method for simulating tire noise performance using a computer includes a step S1 of setting, using a finite number of elements, a tire model having a tread model portion provided with a tread groove, a step S2 of setting a road surface model using a finite number of elements, a step S4 of 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 contact with the road surface model and out of contact therewith; a step S5 of acquiring a surface coordinate value of the tread model portion at least in the groove-grounded rolling distance in a time-series manner, and a step S7 of 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.</p> |
