| Abstract: | Using MSC.Marc,a three-dimensional finite element model of a 800MN forging press was built,different combination modes of the load bearing structure caused by manufacturing errors were analyzed,the law of stress distribution under different combination modes and different load-bearing plate numbers were studied.Finally,the combination law of parallel load bearing structure was set up and laid a preliminary foundation for the stable running of the equipment, which ensured the force flow uniformly. |
