Introduction:

Introducing a CAE program is very effective as it allows evaluation of design proposals without prototyping during product design.

Another issues :

However, is it really effective to perform CAE analysis every time the design plan changes?

Also, which of the analysis results can the engineer refer to whenever he changes the design?

In the image below, you can see the results of each CAE analysis for various designs.

The engineer will select the final design based on the most satisfactory results based on evaluation criteria.

Suggestion topology optimization :

However, repeating [design-CAE analysis] like this takes a lot of time for engineers.

There is one thing to note here.

When an engineer designs to increase the rigidity of a structure, it can be seen that the design form of reinforcement is symmetrical as in the design above.

Could a symmetrical shape be the answer?

Here, the topology optimization analysis, which is the only CAE analysis result that can give insight into the design, was executed and the results were confirmed.

Conclusion:

It can be confirmed that the design proposal output from the topology optimization analysis is not symmetrical.

In other words, topology optimization analysis outputs the geometry based on the boundary conditions and load conditions of the structure. Based on this optimized shape, a design that satisfies the design criteria can be derived.
