中文摘要 | 本論文以有限元素法,對具有非線性阻尼參數的汽車懸吊系統,當行經粗糙路面 時,進行其設計靈敏度分析及最佳化設計。為達成減震之目的,一個整合非線性動態反應分 析。設計靈敏度分析及最佳化設計的數值方法,被發展來應用。為確定此次研究的實用性, 以一個四輪獨立懸吊系統的模型,進行最佳化設計,結果顯示經最佳化後的懸吊系統,可在 特定設計點的加速度反應降低 60 %。 |
英文摘要 | The design sensitivity and optimization of vehicle suspension parameters under excitation caused by road roughness is investigated by finite element method when the nonlinear viscous damping is considered. A numerical approach for vehicle dynamics is developed to determine the nonlinear dynamic response and, the design sensitivity analysis and optimization for vibration reduction can be carried out. For verification of this approach, a four-wheel independent suspension is modeled for linear and nonlinear viscous damping and this model can be applied to road irregularities. The non-optimized and optimized acceleration responses for the two damping are illustrated. The optimized suspension systems give the 60% reduction of acceleration at the design point. |
