Example: Warpage countermeasures for connectors in injection molding.
By collaborating with 3D TIMON, we automatically adjust the thickness of solid element models, thereby suppressing warping deformation.
We will introduce a case where warping was minimized by changing the thickness of solid elements. The analysis was conducted using the "basis vector method," which modifies the shape by moving the nodes of the finite element model without using CAD. Several patterns (basis vectors) of the desired shape were prepared from the initial model and combined. As a result of the optimization, the sum of squares of warping improved by 33% to 4.9480e-004 compared to the initial shape, and the maximum warping amount (mm) improved by 12% to 3.8607e-002.
