Study the Effect of Synchronized Force on Combination Frame Structure of Large Forging Press

Abstract:

In view of the work conditions of eccentric loading in large forging presses, a set of synchronized deviation-rectifying system is necessary. Theoretical analysis and calculation of the synchronized balance force (rectified force) were computed based on static stress analysis theory, and then input into the commercial software MARC to build finite element model for combination frame structure of large forging press, the influence of synchronized force on the stiffness and stress distribution of combination frame structure (C type plates) were studied. Comparison among simulation results under different work conditions and also with experimental results was carried out, which testified the correctness of modeled rectified force equations and the finite element analysis system, and also showed the importance of the synchronization balanced system. The disquisitive work has certain significance for designing the large presses or other type presses with this type of combination structure.
