双偏心摆式飞剪下刀架有限元分析

摘要

根据双偏心摆式飞剪设备的实际尺寸，建立飞剪下刀架的三维模型，利用ANSYS Workbench对下刀架进行有限元分析，将分析结果与理论计算结果进行比较。通过对下刀架的有限元分析，找到下刀架的薄弱环节，对下刀架不满足强度要求的部分进行了改进，保证了飞剪工作过程中下刀架的安全可靠性。%The 3D model of the bottom holder of a double eccentric pendulum flying shear is established with ANSYS Workbench , and the strength and stiffness of the bottom holder is analyzed on basis of the actual dimensions of the pendulum flying shear .The result coming from the finite element method is compared with the theoretical result .Through the finite element analysis ,the weak‐ness of the bottom holder is found out ,and the structure of the bottom holder is improved to ensure the safety of bottom holder in the process of flying shear working .
