ブレーキノイズに関する研究 : 第4報, ディスクブレーキグローン音に減衰の及ぼす影響

Eliminating brake noise generated during brake application is an important issue in the improvement of comfort in a car. We presented the research on the low frequency groan noise at the 3rd report, using the mathematical model without damping. At this paper, we considered the improved model with damping in order to eliminate disc brake groan. According to the above considerations, disc brake groan can not be eliminated by nondimensional damping B ≤ 10-1. And disc brake groan generation is increased by damping order B=10-1. Furthermore, disc brake groan generation can be reduced by damping B ≥ 1, depending on the ratio of two damping factor.
