5 ways to optimize your design
Gauge optimization, size and shape, and shell optimization, can be used to improve an existing design without altering its overall architecture. 3D topology optimization can be used when a significant re-design is desired because it identifies the optimal load paths of a structure and recommend material reduction. The material layout produced in the 3D topology is then interpreted into a concept design which is dimensioned and fine-tuned with the gauge, size, and shape approaches resulting in a final structure.

OptiStruct Lessons Learned from a Cambered Structure with Welds made Post-Decambering using Modchg
Problem Description
- A pre-cambered trailer is loaded to nearly flat under 1g down by a permanent payload (large steel transformer oil reservoir box).
- As the payload is loaded, the trailer is 'de-cambered." They payload is then welded in place to the trailer.
- Other operational load cases are applied as the subsequent load cases to the de-cambering load. Topology optimization is conducted with responses from both de-cambering load case and subsequent load cases.
- All subsequent analysis must take into account the de-cambering held in place by the welds. The de-camber is a "large displacement" formulation and the loading happens via sliding contact with the payload box.
