[Case Study] Shape optimization of an arm considering layout constraints due to component interference.
Shape optimization is suitable for improvements from existing shapes! A case that achieved approximately 40% weight reduction.
We will introduce a case of arm optimization considering interference conditions. To obtain a shape that does not interfere with the area, we create a mesh of the designable region. By designating this model as the "deviation specification area," we optimize it to achieve a shape that does not protrude from this area (does not deviate). As a result, we obtained a lightweight shape that meets various constraints without deviating from the specified area. Shape optimization is suitable for improvements from existing shapes, and by adding multiple constraints such as stress constraints and manufacturing requirements, it is possible to conduct more detailed examinations. *For more details, please refer to the PDF document or feel free to contact us.*
