| Abstract: | In order to solve the problem of easily damaged connecting device between U-foaming machine sword-like beam and oil cylinder on the UOE production line，the structure and force of connecting device were analyzed，the finite element mechanical model of connecting device was established，and the stress condition was simulating calculated and verified. The damage reason of connecting device was found，and the material and structure of easily damaged connecting device were adjusted combined actual production. The practical used results showed that the improved equipment spare parts could meet the mechanical requirements of connecting device well, and no accident of device damage took place. |
