隨著工程領域的研究與發展，近年已有應用多體動力學(Multi-body Dynamics, MBD)與離散元素法(Discrete Element Method, DEM)之雙向耦合分析於抑制齒輪傳遞振動之研究，然而鮮少有關如何產生齒面磨削紋理以降低振動噪音之相關研究。本計畫第一年將透過光學儀器掃描蝸桿砂輪之表面紋理並於程式中建立其拓樸面，更建立創成磨齒機動作以得到研磨後齒輪之齒面磨削紋理，並與實際磨削後之齒面紋理進行比對，以驗證建立理論模型之正確性；在第二年度中，將延續第一年之研究基礎建立具磨削紋理之齒面，基於DEM於齒面上配置離散微粒以逼近齒面磨削紋理，並透過MBD之耦合求解，探討齒面磨削紋理對傳動振動之影響；而第三年度將解析六軸同動磨齒機之機械設定參數，藉以磨削出預期之齒面紋理，並實際於磨齒機上進行齒面研磨，研磨後齒輪對將實際運轉嚙合、以積分式噪音計與三軸振動加速規量測獲得振動及噪音值，透過ArtemiS SUITE軟體分析並模擬除頻後的振動噪音改善成果，再與實驗量測相互比對驗證。本計畫之研究成果及建立技術，預期將可提升國內磨齒機之附加價值，並改善齒輪傳動品質。 ;In recent years, the two-way coupling analysis of Multi-body Dynamics (MBD) and Discrete Element Method (DEM) has been applied to suppress the transmission vibration and noise of gears. However, less research on how to create the gear grinding texture to reduce the transmission vibration and noise so far. In the first year of this project, the worm wheel surface will be scanned by optical instruments and its microscopic surface topography will be established by programming. The gear grinding motion on a generating gear grinding machine will be established to obtain the simulated grinding texture on the work gear tooth surface. The practical gear grinding is planned to conduct for verifying the validity of the theoretical model. In the second year, several micro-granules will be distributed on the gear surface and the coupled DEM-MBD simulation will be applied to analyze the influence of the gear grinding texture on the transmission vibration. In the third year, the machining setting parameters of a 6-axis CNC gear generating grinding machine will be studied for grinding the desired gear grinding texture. The practical gear machining tests using the solved machining settings will also be performed on a gear grinding machine, as well as the transmission vibration and noise of finished gear pairs will be measured by the tri-axial accelerometer and noise-meter. The measured data can be analyzed through the software, ArtemiS SUITE, to evaluate improvement on gear transmission noise. The aforesaid developed technologies are expected to enhance the added value of gear grinding machines and improve the quality of gear transmission in domestic.
