Surface/volume regione in cylinder geometry

Hi,

I have difficult to define a surface/volume regione at 3D part with cylindrical geometry

For example ( in attached file), I would like to apply a bearing load on a surface regione ugual to sum of width of two bearings.

can you help me about it?

 

Thank you.

 

Have a nice day

Re: Surface/volume regione in cylinder geometry

Create a surface in the model that represents the contact area of the bearing race and shaft. You can then apply the load to that region when defining the boundary conditions.

 

You can copy the outer surface of the shaft and then trim that to match the bearing interface. 

Re: Surface/volume regione in cylinder geometry

it's not possible without modification of the 3D model?

Re: Surface/volume regione in cylinder geometry

You can add a surface region to the OD from within Simulate. This way you only modify the geometry as part of the analysis only. Look for the tool that allows you to create a "Surface Region" from within the "Refine Model" tab:

Make sure you also use the "Bearing" load option so the load distribution will be more realistic.

Re: Surface/volume regione in cylinder geometry

I know, but it's not clear for me how to do it with cylindrical geometry.

Thank you

Re: Surface/volume regione in cylinder geometry

It's fairly simple - create a datum plane positioned outside the OD of the shaft and sketch a rectangle on it that will act as a projected "cutter" to slice through the cylinder. Define the width and location of the bearing's size as this sketched rectangle to slice the shaft. You will then need to select the surface(s) that will be intersected by it. That should do it.

 

Good Luck!

Re: Surface/volume regione in cylinder geometry

Hi, 

I don't understand why not create the plane?

What miss?

 

Thank you
