Low DOF Bushing Model Based on A Nonlinear Viscoelastic Constitutive Model of Rubber Materials


To obtain sufficient accuracy for vehicle dynamic performance simulation, it is necessary to consider bushing amplitude and frequency dependency as well as preload effects in the rubber bushing model. Finite element (FE) models are capable of reproducing these characteristics though it is difficult to obtain sufficient calculation accuracy within practical computation time. This paper proposes a new low degree of freedom (DOF) bushing model. The new bushing model exhibits high computational performance while maintaining precision.車両動的性能解析では,結合部品として多く使用される,ブッシュの動的な応答を精度良く再現することが重要となる.また,フルビークルモデルへの適用にあたっては,計算負荷の小さいブッシュモデルが望まれる.そこで,ゴムの非線形粘弾性材料構成則に基づく低自由度ブッシュモデルを提案し,実測との検証を行った.
