Abstract:
1. A method for simulating tire noise performance using a computer, the method comprising: using the computer to perform a step of setting, using a finite number of elements, a tire model having a tread model portion provided with at least one tread groove; using the computer to perform a step of setting a road surface model using a finite number of elements; using the computer to perform a step of carrying out a rolling simulation to roll the tire model on the road surface model at least over a groove-grounded rolling distance where the tread groove is grounded on the road surface model and rolled; using the computer to perform a step of acquiring a surface coordinate value of the tread model portion in the groove-grounded rolling distance in a time-series manner; using the computer to perform a step of setting a sound space region around the tread model portion, the sound space region having a shape changing based on the acquired surface coordinate value of the tread model portion; and using the computer to perform a step of carrying out an aerodynamic simulation using the sound space region, wherein
