Title:
TIRE SOUND RADIATION EVALUATION METHOD
Document Type and Number:
Japanese Patent JP2021092419
Kind Code:
A
Abstract:
To evaluate a contribution of oscillation on a tire surface to sound radiation generating from tires in a rolling motion.SOLUTION: An evaluation method of sound radiation from tires includes the steps of: obtaining a relationship between a sound at a sound source location and tire surface oscillation thereat from a signal of the sound at the sound source location when acoustically oscillating a tire surface standing still by the sound from the sound source, and a signal obtained by measuring the tire surface oscillation generating due to the acoustic oscillation at an oscillation measurement location; causing the tire to roll, and measuring the tire surface oscillation in a rolling motion at the oscillation measurement location, and measuring sound radiation from the tire in the rolling motion at the sound source location; obtaining a calculatory signal at a sound source location of the sound arising from the tire surface oscillation in the rolling motion from a signal of the tire surface oscillation in the rolling motion, and the relationship; and obtaining a ratio of the signal of the sound radiation from the tire in the rolling motion measured at the sound source position, and the calculatory signal at the sound source position of the sound arising from the tire surface oscillation in the rolling motion measured at the sound source position.SELECTED DRAWING: Figure 2
