PREDICTION METHOD FOR OUTSIDE-VEHICLE NOISE OF TIRE AND RECORDING MEDIUM STORED WITH TIRE OUTSIDE-VEHICLE NOISE PREDICTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a prediction method, for the outside-vehicle noise of a tire, in which the level of the in-acceleration outside-vehicle noise of the tire can be predicted with high reproducibility, with satisfactory accuracy and easily. SOLUTION: The in-acceleration outside-vehicle noise of the tire is predicted in such a way that the inertial running noise of the tire generated in a running operation at a prescribed running speed is composited with an in-acceleration noise increase amount generated in an acceleration at the predicted running speed. The in-acceleration noise increase amount is found by using frictional energy which is generated by accelerating the rotation of the tire and which acts between the tire and a road surface or by using frictional power which is generated by accelerating the rotation of the tire and which acts between the tire and the road surface.
