Static and dynamic stiffness analysis and optimization of ring forging is an important part of ring forging process. Static stiffness refers to the resistance of ring forgings to external forces in the static state, and dynamic stiffness refers to the resistance of external forces in the motion state.
For static and dynamic stiffness analysis and optimization, the following steps can be taken:
Static stiffness analysis: According to the geometry, material properties and loading conditions of ring forgings, a finite element model is established for static stiffness analysis. Specifically, it is necessary to discretely divide ring forgings into finite nodes and elements according to the actual situation, and then use appropriate boundary conditions and load conditions to simulate and calculate in finite element software to get the stiffness response of ring forgings under static loading. The purpose of static stiffness analysis is to verify whether the design of ring forgings meets the requirements. If there is a problem of insufficient stiffness, it needs to be optimized.
Dynamic stiffness analysis: Dynamic stiffness analysis takes into account the stress and deformation response of ring forgings during movement. Among them, the inertia force and centrifugal force will affect the stiffness in the state of high-speed motion. Dynamic stiffness analysis can use dynamic method, combined with finite element analysis and dynamic model to simulate the actual motion process of ring forging, and calculate the stiffness response under the motion state.
Stiffness optimization: On the basis of static and dynamic stiffness analysis, stiffness optimization can be further performed. The optimization methods can include parameter design optimization, material selection optimization, process parameter optimization, etc. The goal is to reduce the mass and volume of ring forgings as much as possible under the premise of meeting the strength and stiffness requirements by adjusting the design, material and process factors.
It should be noted that the stiffness analysis and optimization of ring forgings is a complex work, which needs to be completed by professional finite element analysis software, dynamic analysis software and optimization algorithms. In actual operation, it is also necessary to consider the plastic deformation characteristics of the material, heating and cooling process, forming force distribution and other factors to ensure the accuracy and feasibility of the analysis and optimization results.
