dc.description.abstract | 本論文討論慣質在汽車被動懸吊控制上的應用。我們將一個新的機械元件-慣質與傳統懸吊元件結合,套用到汽車懸吊系統中。慣質像彈簧、阻尼一樣,是一個被動式的元件。由於慣質的發明,使得機械網路系統得以完美的對應至電子網路系統。從分析的結果顯示,慣質可以增進汽車懸吊的性能。現今已有數種慣質的實現方式被建立且測試完畢。但由於慣質是一機械元件,所以會導致一些非線性的因素產生。我們將討論三種非線性因素 – 背隙、摩擦力、彈性效應,並將理論推導的結果與實驗所得的結果相互比較,以驗證慣質之性質。最後我們將討論慣質的非線性因素對汽車懸吊系統的影響。結果顯示非線性因素將稍微減少慣質所帶來的效能增益。 | zh_TW |
dc.description.abstract | This thesis discusses the application of Inerter to passive vehicle suspension control. We employ a new mechanical element – Inerter into vehicle suspension systems, combining it with traditional suspension elements. Inerter is a passive element like a spring or a damper. By the invention of Inerter, the mechanical network can be analogous to the electrical network perfectly. From the result of analysis, we find Inerter can improve the vehicle suspension performance potentially. Until now, several realizations of Inerters were constructed and tested. Due to mechanical construction, some nonlinearities of Inerter were noted. We discuss three kinds of nonlinearities – backlash, friction, and the elastic effect, and compare the theoretical and experimental results to verify the property of Inerters. Finally we discuss the influence of Inerter nonlinearities to vehicle suspension performance. It is shown that nonlinearities slightly decrease the performance benefit of Inerters. | en |
