概要

• 論文の詳細を見る

• The mechanism of specific squeal frequency was investigated by an apparatus with a steel rod and a thin steel disk. Squeals of higher modes occur in rods with smaller sectional areas and squeals of lower modes occur in large rods. Squeal is generated at specific contact positions on a rod. From the theoretical results, it was found that a squeal of the frequency near the contact frequency of the rod and disk occurs. The theoretical results on squeal frequency agree with the experimental results. Thus, squeal frequency for any contact load and position can be predicted theoretically.
