Mechanical seals are used to prevent leakage of liquids and gases in rotary mechanisms in various industrial fields. A mechanical seal consists of a rotating ring and a stationary ring, which make a surface contact. Mechanical seals could generate friction-induced vibration under rotary sliding motion, leading to unexpected noise. The uncomfortable sound significantly decreases the product value even if the sealing performance is acceptable. Tadokoro et al. proposed an anti-vibration method using Yaw Angle Misalignment effect (YAM method), which applies a parallel misalignment to a rotary sliding system, leading to suppress friction-induced vibration. In this study, to investigate the effect of the YAM method on suppression of friction-induced noise in mechanical seals, the YAM method was applied to two types of mechanical seals in which the rotating ring was the source of vibration and mechanical seals in which the stationary ring was the source of vibration.
