摘　　要：16开折刀的设计影响轮转机折页的精度、速度和稳定性。而16开折刀结构复杂,运用一般力学方法很难全面求解出16开折刀的应力及变形情况。采用有限元法,合理地分析折刀在工作过程中的承载情况,再通过ANSYS软件建模分析,可以方便快捷地解决16开折刀的应力与变形问题。通过对其应力与变形情况的分析,能够为16开折刀结构设计提供有益的依据,从而达到提高轮转机16开折页精度和稳定性的目的。从设计实例,可以发现刀杆的强度是满足要求的,刀杆的刚度稍显不足,会影响折页精度。The design of fold knife influences the precision,velocity and stability of the web press folder.For the variable structure of fold knife,it＇s hard to solve the status of the stress and distortion by the normal mechanical method.But by the finite element analysis and ANSYS software,it＇s convenience to solve this problem based on the reasonable analysis of the load in working state.It can supply the favorable bases to the design of web press＇s fold knife by analysing the stress and distortion,for attaching to the goal of increasing the precision and stability of the web press.The example concludes that the intensity of fold knife meet the requirements sufficiently,but the stiffness is insufficient softly,which influences the folding precision.
