摘　　要：通过建立刀具主轴模型,利用SolidWorks Simulation软件进行网格划分,设置边界条件并施加载荷,进行了刚度、强度及模态分析。对开榫刀具主轴的静态特性有限元分析表明,刀具主轴加载后的位移出现在主轴的右侧上部,最大位移为0.016 73 mm,符合变形误差要求;主轴的最大应力出现在安装皮带轮的键槽上部,数值为78 961 616.0 N/m^2,小于屈服应力,满足设计要求。通过对开榫刀具主轴的模态分析得到主轴的前五阶固有频率,机床的固有频率低于主轴的一阶固有频率就可以避免引起机床的共振。Through a tenoning tool spindle model establishment,grid division using SolidWorks Simulation software,boundary condition setting and load application,stiffness,strength and modal analysis is made. The tenoning tool spindle finite element analysis shows that after loading,the displacement of the spindle occurs on the upper right side of the spindle,with the maximum displacement being 0. 016 73 mm,consistent with the deformation error requirements;the maximum stress occurs in the upper part of key slot for pulley installation,with its value being 78 961 616. 0 N/m^2,smaller than yield stress,consistent with the design requirements. Through the modal analysis of the main spindle,the first five-order natural frequencies of the spindle are obtained. When the natural frequency of a lathe is lower than the natural frequency of one order of the spindle,is smaller than the satisfies the design request. Starts out from opposite directions folio the tenon cutting tool main axle the modality analysis to obtain the main axle first five step natural frequency,when the engine bed natural frequency is lower than the main axle a step to be possible to avoid causing engine bed resonating. the resonance of the lathe can be avoided.
