Abstract

Among many kinds of phenomena concerning ride comfort, this paper focused on one issue, which is called Hyoko- hyoko in Japanese and which happens on smooth looking surfaces on motorways. We identify the Hyoko-hyoko, clarify the mechanism of the Hyoko-hyoko by using simple quarter car models, and suggest measures e.g.; suspension stiffness, damping coefficient, to reduce it without sacrifice of the other ride issues.
