Learn about structural constraints and loads.
- [Instructor] Fusion 360 includes computer aided engineering tools as well. Depending on the version of Fusion 360 you have you could be executing a static stress or a structural buckling study just about as easy as creating a fill it. First step in creating a finite element analysis in Fusion 360 is to change the workspace. To do this go to the tool bar and use the workspace dropdown to select simulation. When you enter the simulation workspace for the first time you're offered a selection of what type of study you'd like to execute.
In this case, we'll use static stress. And when it loads the environment you'll see that it changes the toolbar as well as changes the browser. The first thing that I'd like to do is override my standard units by changing the force units to pound force. We'll work our way down the toolbar from left to right setting the material for the study. We could use the same material that the part is currently made of but I'd like to change this to a cast iron.
We can also change the calculation method for the safety factor. We'll leave this as is for now and click okay. You'll see that the appearance updated based on the change of material. Next I'd like to apply a structural constraint. The first one we'll apply will be to this curved surface. Which will be pushing down on the ball joint. It'll be a thick surface but we want to allow it some flexibility. Then we'll apply another structural constraint creating a pin constraint where the actual pin will go through.
And then we'll apply our load. It will be a structural load a standard force being applied directly at the recess of 300 pounds. Once this is done we can see the pre-check is showing a green check mark so Fusion 360 believes it's ready to create a solution. And then we'll choose solve. We have the ability to solve on the cloud or to solve locally. For modest systems, or for complex problems, cloud solution give you a lot of flexibility.
Once I start the study, I can close the dialog and simply wait for the result to appear. This includes the ability to close Fusion 360 or switch to another application. Your system will not be burdened while the cloud solution is being generated. When the simulation is complete you'll get a results details dialog that will give you the minimum safety factor. Here it's showing it's green which is getting pretty close to the minimum level that I would want but it does exceed it.
I'll close this dialog to take a closer look at the results options. We can see that the image of the model has been deformed. We can switch the display to see the stress levels. And we can use the arrows on the legend to focus in on the areas of peak stress. We can also display what the displacement is. While this looks very very bad, it's important to always look at the numbers. This model would be deforming just a little more that half a millimeter under that load.
Which is more than acceptable. We can share these results with others or we can duplicate the study and explore different materials. The type of advanced engineering tools integrated into Fusion will continue to expand over time. And understanding how to properly use them takes more than just knowing what the options do. Still having access to them coupled with the ability to offload the calculations to the cloud is a tremendous asset when used correctly.
