The invention provides a mute tire and a mute tire quality control method and system.The mute tire comprises a tire body and a mute piece attached to the inner surface of the tire body in the circumferential direction, and the tire body is provided with a static unbalance light point and a static unbalance mass M, the middle point of the mute piece in the length direction is located on a static unbalance light point of the tire body, the attaching length of the mute piece is c1, and the distance between the head end and the tail end of the mute piece is c2; wherein the fitting length c1 of the mute part is equal to 2 * pi * (r-a/2)-c2, in the formula, c2 is equal to M/(rho * a * b), rho is the density of the mute part, a is the thickness of the mute part, b is the width of the mute part, and r is the radius of the tire body. By means of the scheme, the quiet unbalance of the silent tire can be effectively improved, the yield of finished silent tires is increased, and the purpose of guaranteeing acoustic comfort and mechanical comfort at the same time is achieved.
本发明提供一种静音轮胎、静音轮胎的质量控制方法及控制系统,静音轮胎包括轮胎本体及沿周向贴设于轮胎本体的内表面上的静音件,轮胎本体具有静不平衡轻点及静不平衡质量M,静音件长度方向的中点位于轮胎本体的静不平衡轻点上,静音件的贴合长度为c1,静音件的首端和尾端之间的距离为c2;其中,静音件的贴合长度c1=2*π*(r‑a/2)‑c2,式中:c2=M/(ρ*a*b),ρ为静音件的密度,a为静音件的厚度,b为静音件的宽度,r为轮胎本体的半径。通过以上方案,可以有效地改善静音轮胎的静不平衡性,提升静音轮胎成品合格率,达到同时保证声学舒适性和机械舒适性的目的。
