Rubber Bush Model for Suspension Dynamics Design


To improve ride comfort at smooth road, rising part of hysteresis on suspension wheel stroke curve has to be designed to avoid an increase of dynamic stiffness at very low amplitude due to friction. Rubber bush is one of components that cause hysteresis. However, there is no appropriate method to investigate the influence on dynamic performance of suspension system by designing specification. This paper proposes a rubber bush model that is used for suspension dynamics design in early phase of vehicle development by investigating dynamic specification of rubber bush without detailed design.良路における乗心地性能向上には,フリクションによる微振幅域での動ばね定数の上昇を抑制するため,ヒステリシス特性の立ち上がり形状を滑らかにすることが必要である.本論文では,ヒステリシスの一要因であるラバーブッシュの動特性寄与を初期段階の性能設計においても検討可能なモデル化手法を提案する.
