應用非線性元件於隔振之效應分析及驗證研究
The Analysis and Experimental Verification on Vibration Isolation by Employing Non-linear Elements
摘要
被動式隔振目前廣泛應用於工業界，然而被動式隔振卻有頻寬固定的缺點，為了改善此一缺點，過去之研究曾以參考現有的漸弱性非線性元件加以改良測試，結果發現效果相當好，不過，所謂的漸弱性非線性元件都不易有效的掌握。有鑑於此，本研究有系統地以CAD/CAE工具，分析歸納出漸弱性非線性元件組，並之後將此一元件實現於隔振器中，透過預壓非線性元件即可調整隔振器之自然頻率，在振動環境不變的情況下，提高隔振效果。由實驗結果可知，隨著預壓量的增加，隔振效果可逐漸提高，而預壓量10 mm所得到的隔振效果為沒預壓時的4倍以上，驗證了漸弱性非線性元件可將系統的自然頻率往低頻方向調整，提高隔振器的隔振效果。

The passive vibration isolator is an effective vibration isolation technique but inflexibility to the environments or occasions. In order to improve the deficiency, this study employed non-linear elements in the self-design vibration isolator. First all, confirming the elements had the non-linear property by FEM. The analysis result showed that it can be used to tune the natural frequency by pre-loads. After the practical experiments, all the results showed that the vibration isolation capability can advance with pre-loaded. Furthermore, the isolation capability with 10 mm pre-loaded degrees has four times better than without pre-loaded. The remarkable vibration reduction in some frequency bands has been observed.
