摘　　要：在ANSYS软件中建立了标准渐开线齿轮与修形齿轮的动力接触有限元模型。利用ANSYS/LS-DYNA的显式动力学计算方法,对不同转速下的齿轮副进行了动力接触分析,得出标准渐开线齿轮由于弹性变形导致较大的啮入冲击,齿轮修形后啮入冲击得到明显改善。齿轮啮合动力接触有限元仿真方法对合理确定齿轮修形量,减小齿轮动载荷具有重要理论意义。The dynamic contact finite element models of standard involute gear and modification gear are established in the software of ANSYS. Based on the explicit dynamic formula of ANSYS/LS-DYNA, the dynamic contact analysis of gears under different rotation speeds is completed. It deduces that the elastic deformation of standard involute gear teeth leads to bigger meshing-in impact and it gets obviously better after tooth modification. The dynamic contact emulation method of gear transmission has important theory significance to ascertaining a gear modification amounts and diminishing the gear dynamic load.
