Tire Tread Pitch Noise Control System by Random Arrangement of Circumference Direction Straight Type Groove

원주방향 직선형 그루브의 랜덤배열에 의한 타이어 트레드 피치 소음 제어 시스템

An assessment of a mathematical method of synthesing tire tread pitch noise spectra is studied. The method is based on the summation of phasors and the calculated spectra are conveniently generated as computer printout in the form of bar graph. The technique, its usefulness, its limitations and the implications of using such a model are discussed. This paper presents a basic study on optimum pitch arrangement for prediction and control of tire tread pitch noise in constraint condition relatied with tire properties, thus enabling optimum tread pitch arrangements to be determined at the design stage, by application of old tire tread pitch simulation.
