Shape Optimization of a wheel

[marco_russo37]

Hello,

I am not very familiar with Topological Optimisation, so I apologise in advance. I am trying to perform topological optimisation of this wheel, but how can I associate a portion of the outer rim as preserved geometry? If I select the cylinder, it takes the whole wheel.

Thank you.

Hi @marco_russo37,

The easiest way is to modify the Simulation Model geometry, so that it separates the portion(s) to keep from the portion to optimize:

1. Enter the Simplify workspace
2. Create a sketch and draw a circle at the border where you want to preserve geometry
3. Modify Panel > Split > Split Body using the splitting tool created in step 2.

Then, ensure the Target Body selection has the correct body selected. It may be a toss-up which body persisted with the Target Body designation after the split. If all looks good > Generate Automatic Contacts > Send the study to solve.

Hope this helps! Please let us know if you have any additional questions, comments or suggestions.

Hi thank you for your answers.

I have another question though. I should simulate the dynamics of the rotation and perform topological optimisation on this. Do you know any guides from which I can take inspiration?

Hi @marco_russo37,

Unfortunately, I'm not aware of any Shape Optimization guides or tutorials that are particular to angular rotation, or topology optimization of a wheel.

If there is documentation, I'd presume they'll use the Global Angular load which can define either an angular velocity, angular acceleration (or both) to all bodies.

If you're primarily interested in the resulting shapes, Generative Design has been used to design the wheels and steering wheel of their microbus concept. I'm not sure what was involved with creating the final outcome shapes.
