本研究旨在探討高精密平面磨床的靜動態特性，使用有限元素分析法(Finite Element Analysis, FEA)對整機進行靜剛性與動剛性分析，再透過實驗模態分析(Experimental Modal Analysis, EMA)與操作變形振型(Operational Deflection Shapes, ODS)量測實際振動特性並且加以驗證。本研究亦搭配拓撲最佳化進行結構剛性強化，避免機台產生共振現象導致精度損失，以滿足現代工業製造的需求。透過模態分析和實際量測結果，觀察高精密平面磨床的前兩階自然頻率分別為68.2Hz和73.0Hz。進一步利用EMA與ODS進行量測加以驗證，於前六階模態中，對比誤差皆低於10%。這強化了分析結果的可信度和準確性。為了輕量化整體結構，利用ANSYS Workbench針對底座、立柱和主軸外殼進行拓撲分析與結構優化，使整機的總體質量減少了6.2kg，主軸的位移量降低了1.7%。同時，整體結構的前六階自然頻率分別提升了3.7%、2.5%、5.3%、0.7%、2.1%和4.1%。並且第一階模態提升至70.8Hz，成功避免了在3600rpm下的頻率區間（60Hz至70Hz）內的共振，達成了結構的輕量化與提升剛性之目標。利用RecurDyn對高精密平面磨床的主軸座與工作床台進行了有緩衝與無緩衝控制的運動模擬。透過模擬運動控制的差異，確保了機台運行的穩定性，更進一步掌握機台之實際運動特性。.

520 3 $a This study aims to investigate the static and dynamic characteristics of a high-precision surface grinding machine. Finite Element Analysis (FEA) is employed to perform both static and dynamic stiffness analyses on the entire machine. Experimental Modal Analysis (EMA) and Operational Deflection Shapes (ODS) measurements are carried out to validate the actual vibration characteristics. Topology optimization is employed to enhance the structural stiffness in this study, thereby reducing the risk of resonance-induced accuracy loss and ensuring compliance with the exacting demands of contemporary manufacturing standards. The initial two natural frequencies of the high-precision surface grinding machine were determined to be 68.2 Hz and 73.0 Hz through modal analysis and experimental testing. Utilizing ODS and EMA measurements for the initial six modes, further validation produced ensures with less than 10% error. Topological analysis and structural optimization with ANSYS Workbench led to a significant 6.2 kg reduction in mass and a 1.7% decrease in spindle displacement. The structure demonstrated improvements of 3.7%, 2.5%, 5.3%, 0.7%, 2.1%, and 4.1% across the initial six natural frequencies. Elevating the initial modal frequency to 70.8 Hz effectively averted resonance in the 60 Hz to 70 Hz range at 3600 rpm, highlighting enhanced weight efficiency and increased stiffness. RecurDyn simulated spindle seat and worktable motion control, with and without buffering, the stability of machine operation is ensured, providing a deeper understanding of the actual motion characteristics of the machine..
