| dc.description.abstract | 阻尼顆粒技術應用於齒輪傳動系統中能有效降低齒輪傳動過程中之振動，其透過顆粒－顆粒及顆粒－齒壁之間的摩擦與非彈性碰撞消耗能量。本文基於多體動力學(Multi-body Dynamics, MBD)與離散元素法(Discrete Element Method, DEM)雙向耦合理論提出一具阻尼顆粒齒輪傳動系統之動力學模型，透過輸出軸之振動加速度計算結果，評估加入阻尼顆粒後齒輪傳動系統之抑制振動效果。本研究更建立齒輪動力量測試驗台，透過量測軸承座上之振動加速度，分析齒輪系統在加入不同阻尼顆粒配置、不同轉速下之振動響應。針對理論模型之計算結果與抑振量測實驗結果進行探討及分析，證實阻尼顆粒能有效抑制齒輪傳動時之振動，在不同轉速、粒徑、顆粒填充率下，理論計算及實驗量測結果之減振程度具有一致性。 | zh_TW |
| dc.description.abstract | As is known, adding the damping particles in the gear transmission system can effectively suppress vibration during the operation process, because vibration energy is dissipated through the damping mechanism of particle collision and friction. This study has established a dynamic model for a gear transmission system containing damping particles, based on the two-way coupling of multi-body dynamics (MBD) and discrete element method (DEM). The translational acceleration of output shaft is analyzed to evaluate the effectiveness of vibration suppression for a gear transmission system with particles. In addition, a test platform for measuring the dynamic responses of a gear pair is constructed. The linear acceleration on the bearing seat of output shaft is measured to analyze the vibration responses of the gear system with different rotational speed and different particle settings. The results from the proposed model and the experimental measurements are further discussed and investigated to prove the consistency of degree of vibration suppression in consideration of different rotational speed, particle radius and particle filling rate. | en_US |
