The intent is to let ANSYS come up with an optimal shape for the bracket connecting the two sides of the fork. A single set of loads can be used, or multiple load cases can be defined. All or a portion of the load cases can be utilized in the topological optimization, and weighting factors can be used on each set of loads if needed. Block A is the standard static structural analysis on the original, starting geometry. This includes all load cases needed to describe the operating environment.

Block B is the actual topological optimization. Block C is a validation study, performed on the optimized geometry. This step is needed to ensure that the optimized shape still meets our design intent. Within the topology optimization, we set our objective. He we choose minimizing compliance, which is a standard terminology in topology optimization and we can think of it as the inverse which is maximizing stiffness.

In the static structural analysis, 7 load cases were used to describe different loading situations on the motorcycle fork, and here all have been used in the optimization. That will keep the topology optimization from making regions that are too small to 3D print or otherwise manufacture. Here we have specified a minimum member size of 0. Since the topological optimization solution uses the same ANSYS solvers for the finite element solution as a normal solution, we can leverage high performance computing distributed solvers, typically to speed up the solution process.

Multiple iterations are needed to converge on the topology optimization, so realize that the topo opt process is going to be more computationally expensive than a normal solution. Notice that only a portion of the original model has been affected. ANSYS allows us to specify which regions of the model are to be considered for optimization, and which are to be excluded.

Now that we have a shape that looks promising, we still need to perform a validation step, in which we rerun our static simulation with the loads and constraints we expect the fork assembly to experience. The images shown above show the mesh information that results from the topo opt solution. As you can see in the above image, SpaceClaim automatically has the original geometry as well as the new, optimized shape.

We can do as much or as little to the optimized shape as we need, from smoothing and simplification to adding manufacturing features such as holes, bosses, etc. In this case we simply shrink wrapped it as-is. Continuing with the validation step, the geometry from SpaceClaim automatically opens in the Mechanical window and we can then re-apply the needed loads and constraints and then solve to determine if the optimized shape truly meets our design objectives.

If not, we can make some tweaks and run again. The above image shows a result plot from the validation step. The geometry efficiently comes through SpaceClaim from the optimization step to the validation step. If not, then perhaps what you have seen here will spark a craving to learn.

Hopefully those examples show there can be variation in the design of this brace, while not largely tampering with the musical performance of the saxophone in general.

The intent was to pick a saxophone part that could undergo topological optimization which would not significantly alter the musical characteristics of the instrument. The first step was to obtain a CAD model of a saxophone body. Since I was not able to easily find one freely available on the internet that looked accurate enough to be useful, I created my own in ANSYS SpaceClaim using some basic measurements of an example instrument.

The idea is that the topological optimization process will remove non-needed material from this blob, leaving an optimized shape after a certain level of volume reduction. In ANSYS Mechanical, the applied boundary conditions consisted of frictionless support constraints at the thumb rest locations and a vertical displacement constraint at the attachment point for the neck strap. Acceleration due to gravity was applied as well.

Other loads, such as sideways inertial acceleration, could have been considered as well but were ignored for the sake of simplicity for this article. Now that things are looking as I expect, the next step is performing the topological optimization. I set the Design Region to be the blog of material that I want to end up as the optimized brace. I did a few trials with varying mesh refinement. Obviously, the finer the mesh, the smoother the surface of the optimized shape as elements that are determined to be unnecessary are removed from consideration.

The optimization Objective was set to minimize compliance maximize stiffness. On the other end, the patch has been split through the middle, making it look something like an alligator clip. Another optimization run was performed in which the solder pads were held as surfaces that were not to be changed by the optimization.

The resulting optimized shape is shown here:. And here is the result of the topological optimization using the thinner blob as the starting point:. Another option is to fit geometry in a more general way in an around the faceted result. These methods can also be combined. SpaceClaim is really a great tool for this. I then checked the displacement and stress results to see how they compared.

First, we have an organic looking shape that is mostly faithful to the results from the topological optimization run. The next candidate is one where more traditional looking solid geometry was created in SpaceClaim, using the topological optimization result as a guide. This is what it looks like:. Next, here is the deformation result for our simple loading condition using this second geometry configuration:.

The third and final design candidate uses the second set of geometry as a starting point, and then adds a bit of style while still maintaining the topological optimization shape as an overall guide. Again, I want to emphasize that this was a simple example and there are other considerations that could have been included, such as loading conditions other than acceleration due to gravity. It is my hope that you will also explore what can be done with this tool.

Regarding this effort, clearly a next step would be to 3D print one or more of these designs and test it out for real.
