Abstract：

The prestressed tie rod is an important part and the key force components of full preload combined frame for forging press. Therefore, in order to research the real deformation condition of tie rod during the actual working for fast forging hydraulic press and the preload state of combined frame, the strain of pull rod for 45 MN hydraulic press under the rated working condition was tested by patch test, and the static structure simulation of full preload combined frame under the same working condition as the test was carried out by software Ansys. Then, the test and simulation results were compared and analyzed, and the real strain and displacement amount of the rod in operation were obtained, which verifies the credibility of the finite element analysis and provides theoretical basis and data support for the hydraulic press design and the preload process of tie rod. Furthermore, combining the theoretical calculations, finite element simulation and on-site measured data, the real deformation state of tie rods in operation was analyzed, and the actual preload level of frame was grasped by using three theoretical and measured tooling methods to verify each other.
