Topology optimization appears after size optimization and shape optimization
A new structural optimization method is quite popular in the field of structural optimization
Challenging research directions. It corresponds to the conceptual design level of product design
Generally, a nonsmooth approximate boundary can be formed and the junction can be predicted
The best force transfer path (strength topology optimization) or better stiffness
Distribution form (stiffness topology optimization). The result of topology optimization passes through the edge
After the boundary smoothing technology processing and CAD solid model reconstruction can be converted
In the stage of shape optimization and size optimization (detailed design stage), therefore
A complete optimization design process includes the above three stages. continuity
For topology optimization of bulk structures, the common material interpolation models include uniform
