Abstract:	本研究在分析單級增速螺旋行星式齒輪箱模態與動態特性，分別應用可考慮時變剛性之等效離散模式與有限元素連體模式來分析單階齒輪箱之動態響應與模態特性。在離散模式方面，先計算螺旋齒輪對的時變等效嚙合剛度、包括齒輪嚙合相位與組裝關係，也加入軸承、輸出入軸與齒輪箱體剛度模式，可建立單級螺旋行星齒輪系之時變離散分析模式，然後加入施於風力機運轉的輸出入軸變動扭矩並進行數值求解，以計算行星齒輪系統的動態響應，獲得動態齒輪與軸承負載或應力，另外將自然頻率與模態結果與LS-DYNA有限元素的結果進行比較驗證。初步獲得兩種運轉負 This study investigates modal and dynamic characteristic of a single stage planetary gear system under dynamic excitation. Two approaches which respectively use a discrete and a finite element model are used to obtain modal and dynamic responses. In the d
