近年來捷運系統成為大眾運輸之主要交通工具,其安全性與舒適性至為重要。車廂振動之主要自由度包括前後與上下的位移,俯仰與滾轉,本研究旨在採用具代表性之單節車廂剛體模式,探討掛載被動與主動調諧質量組尼器(Tuned Mass Damper ;TMD) 進行車廂動力系統在自由振動及各種外力作用下振動抑制之可行性,其中主動控制並分別採用最佳控制與模糊控制。再進一步探討捷運車廂受到側向風力採用 TMD 對滾轉振動之效果,最後並引用三節車廂剛體模式分析列車不同車廂組合之動力行為。首先分別建立單節車廂與三節車廂之剛體模型來描述包含車廂、懸吊系統、調諧質量組尼器之結構動力系統,進一步以狀態空間表示,再以Runge-Kutta方法求解包括自由震動、步階外力、諧和外力、與El Centro 地表加速度作用下時間解域之未控制或受控制系統之歷時反應;被動控制方面藉由調整TMD的參數來尋找最佳的TMD參數值,主動控制方面採用最佳控制及模糊控制進行狀態回饋控制,消減外力激擾下捷運車廂之動力反應,結果證實適當調整TMD的參數、選擇最佳控制權值矩陣( 和 )、適當的歸屬函數與模糊規則庫,皆能有效的達到良好的控制效果,此外亦證實主動TMD比被動TMD有更好的抑制振動能力。
Recently the rapid and mass transit system (RMT) has become the major transportation tool for daily use and its safety and comfort is very important to people. The oscillation of cars of RMT can be described in forward/backward translation, vertical translation, pitching and rolling modes. This thesis is proposed to study the application of passive and active tuned mass dampers (TMD) to the cars of RMT subjected to free vibrations and various forced vibrations using the typical single-car rigid model, wherein optimal and fuzzy control strategies are involved in the active control synthesis. Further, the dynamic responses of rolling mode of uncontrolled and controlled cars subjected to lateral winds are studied. Then, three-car rigid-body model is employed to investigate the different arrangement of cars of a train. The equations of motion of rigid-body models for single-car and three-cars cases are derived and then expressed in state space form. The time-domain responses of the vehicle dynamic systems are solved using Runge-Kutta scheme. In passive control various parameters of TMD would be investigated. Both optimal control and fuzzy control schemes would be adopted in the active control synthesis. It is concluded that adequate selection of TMD parameters, weighting matrices in optimal control and membership functions and rule banks the oscillation of cars of RMT would be alleviated by the use of passive and/or active TMD. It is also found that active control is better than passive one.
