Abstract:
Aimed at the auxiliary tooling truss for installation of 800 MN forging press, which is the largest in the world, steel structure design calculation and finite element analysis research were conducted. Firstly, a 3D solid model of tooling truss was designed and built using the Solidworks software. Secondly, according to the model structure and geometrical parameters, a simplified model for finite element analysis was built with ANSYS. Then, the stress, displacement contour diagrams and displacement-load curves were obtained by analyzing the load, with strength, stiffness and stability considered during the most dangerous working conditions. The results show that the maximum stress and the maximum deflection of tooling truss are respectively less than the allowable stress and allowable deflection.The safety coefficient of working stability is far more than the safety coefficient of allowable stability. Finally, the rationality, safety and reliability of the design of tooling truss are further verified by the success of the forging press installation. 18 figs, 10 refs.
