[Case Study] Stress Reduction through Optimization of Fillet Shape ★ Detailed Materials Available
Focusing on the fillet section of the wrench component, we reduce the generated stress concentration! We guide it to an optimal shape that meets manufacturing requirements while maintaining a uniform R shape.
We would like to introduce a case study on the optimization of fillet shapes aimed at stress reduction. Taking manufacturing requirements into account, we sought a shape that minimizes stress while maintaining a uniform R shape. As a result, due to the axial symmetry setting, we were able to alleviate stress while preserving symmetry. Typically, when evaluating and optimizing local stress, the shape does not remain symmetric. However, with "OPTISHAPE-TS," it is possible to optimize while considering symmetry, allowing for changes in shape while maintaining the symmetry of the R shape, as in this case. [Case Overview] ■ Analysis Model - Elements: Tetrahedral second-order elements - Number of elements: 220,782 - Number of nodes: 324,937 ■ Result: Stress was alleviated while maintaining symmetry due to the axial symmetry setting. *For more details, please refer to the PDF document or feel free to contact us.
