Simulation analysis and optimization design method of shaft forgings

The simulation analysis and optimization design of shaft forgings refers to the virtual simulation through computer aided engineering (CAE) software, and the optimization design of the structure and process parameters of the forgings through the analysis results. This method can effectively reduce trial and error costs and save time, improve production efficiency and product quality.

The following is the method steps of simulation analysis and optimization design of shaft forgings:

1. Establish geometric models: Use CAD software to establish geometric models of shaft forgings, including their shape, size and orifices. According to the actual situation to determine the material properties of forging.

2. Mesh division: The geometric model is discretized into finite element mesh, usually using professional finite element analysis software for mesh division. It is necessary to consider the special geometric features of shaft forgings, such as orifices, curves and cross section changes.

3. Material model definition: According to the selected material type, select the appropriate material constitutive model. The commonly used material models are elastic model, plastic model and constitutive model. According to the stress state of shaft forgings, a suitable material model is selected for calculation.

4. Boundary conditions and load setting: Determine the boundary conditions and force conditions of shaft forgings. According to the requirement of practical application, the information of constraint condition, load size and direction of shaft forging is given.

5. Simulation calculation: The finite element analysis software is used to simulate the shaft forging. According to the boundary conditions and load conditions, the stress, strain and deformation parameters of shaft forgings under static or dynamic loading are calculated by finite element method.

6. Evaluation of analysis results: Evaluate the performance and stability of shaft forgings according to the simulation results. Focus on stress concentration, deformation, safety factor and other indicators to evaluate the structure of forging.

7. Optimization design: According to the analysis results, appropriate optimization measures are taken to improve the design of shaft forgings. Possible optimizations include adjustments to geometry, material selection, processing and process parameters. The simulation calculation is carried out again, and the performance difference of different design schemes is compared, and the best design scheme is selected.

8. Verification and verification test: Finally, verification and verification test are carried out on the shaft forgings after optimization design. The accuracy and reliability of the simulation are verified by comparing the experimental data with the simulation results.

It should be noted that the simulation analysis and optimal design of shaft forgings is a complex project, which requires professional knowledge and experience in related fields. In practical applications, factors such as material authenticity, process feasibility and cost effectiveness should also be considered. Therefore, it is recommended to seek the support of a professional engineer or team to ensure the accuracy and effectiveness of simulation analysis and optimized design.
