Set up a static stress simulation.
00:05
After completing this video, you'll be able to
00:08
define simulation study settings, set up loads and constraints,
00:12
clone a load case and define study materials
00:17
in fusion 360. We want to begin with the supply data set, static stress setup dot F 3D.
00:22
If you followed along in the previous video for preparing a simulation study,
00:26
you can also carry on with your own data set.
00:30
What we want to do in this video is talk about defining simulation study settings.
00:34
We want to set up our loads and constraints,
00:36
clone load cases and define our study materials.
00:40
The first thing that we want to do is under our study drop
00:43
down note that we have the ability to create new simulation studies,
00:47
the simulation studies will all be contained in the same simulation workspace.
00:51
So if you need to run multiple study types on your designs, you can do it from there.
00:57
The other thing that we want to note before we get started is
00:59
under the manage we have settings that affect the overall simulation study.
01:04
When we go into our settings,
01:05
we have a couple of different options.
01:08
We have a remove rigid body modes which will not be using in this video.
01:12
But if we use that, we need to ensure that all the loads on our design are balanced.
01:16
We have mesh settings which by default will create a mesh on the design,
01:20
but we can have advanced settings or use a per part mesh size.
01:25
This is helpful if we're simulating an
01:26
entire assembly that has multiple bodies or components
01:30
for. Now, we're going to leave these all as default
01:32
and note that we do have an adaptive mesh refinement
01:36
because we took the time to remove all of the small filets on this design.
01:40
We don't have to worry about mesh element
01:42
sizes for small filets because they're all gone.
01:45
But if you had a design where the filets were going to be a critical aspect,
01:49
it might be important for you to use adaptive mesh refinement.
01:53
Now that we've taken a look at some of the basic settings.
01:56
Let's go ahead and focus on first setting our study materials
02:00
by default, it'll be using the same as model.
02:03
So if you set your physical material in the design workspace, it'll carry over here
02:07
by default Fusion 360 designs are set up with a steel material.
02:12
This is what we're going to use for our design.
02:14
So we're going to leave this as default.
02:16
But also note that you can change the safety factor
02:19
whether it's calculated from the yield or the ultimate tensile strength
02:23
we'll be using yield as our default setting and say, OK,
02:27
next, we want to talk about setting up our loads and constraints,
02:31
the loads and constraints will determine how this design is being interacted with.
02:36
So we're gonna start by selecting structural constraints
02:39
and instead of a fixed type, we're gonna be using a pin constraint.
02:43
When we select pin constraint, we have three options
02:47
by default radial and axial will be toggled on preventing
02:50
the selected faces from translating out radially or axial.
02:55
This is exactly what we want in this instance,
02:58
we're gonna select the two inside faces of these bosses. And we're gonna say, OK,
03:03
next, we want to add a structural load.
03:06
The structural load is going to be using a bearing load type.
03:09
There are multiple types of load cases
03:12
and it will be important to understand the physical interaction
03:15
that your design will have with the outside environment.
03:18
In
03:18
this case,
03:19
a bearing load makes the most sense because it creates
03:22
a parabolic distribution along half of our cylindrical face.
03:27
We're going to start by rotating this around and noting
03:29
that there are some small arrow icons on the screen
03:32
and we're gonna rotate this 90 degrees.
03:36
We're gonna change the default units to pound force
03:39
and we're gonna set the magnitude at 500.
03:42
If you want to stick within the metric system,
03:45
£500 force is roughly equal to about 2224 newtons.
03:51
A fusion doesn't care if you use newtons or pound force,
03:54
you can convert back and forth between them.
03:57
So if you know your units in one system of measurement, you can use that,
04:01
this is going to apply a £500 force on the right half of the cylinder
04:06
using that parabolic distribution with the most amount
04:09
of load being focused in the center.
04:11
And this is traditionally how these loads would be applied to cylindrical faces.
04:16
If instead we had used a force type of load,
04:19
the force would have been evenly distributed along the entire face.
04:23
This means even though the force is going in the positive X direction,
04:26
it would also be pulling along that back section of the cylinder.
04:30
This is why it's important to understand the loads and constraints on your design
04:34
to make sure that you get the most accurate results.
04:38
Now that we've set up our first load case, let's go ahead and select the load case
04:42
and I'm going to rename this 90 deg
04:46
that tells me that the load is at 90 degrees.
04:49
If I want to reuse any of these settings,
04:52
I can right click on this load case and I can clone it
04:55
when I clone a load case, I want to activate it.
04:58
I'm gonna start by renaming this 45 DEG
05:02
and I want to expand my loads and edit my bearing load.
05:07
Next, we want to rotate this to an angle of 45 degrees and say, OK,
05:12
by cloning our load case, we were able to create an exact copy of what we had done.
05:18
If you have a complex model that has a lot of loads of constraints,
05:21
this can be extremely efficient way to reuse that data.
05:25
Also note that we have options to clone the entire simulation study.
05:30
And we're gonna be talking about that in a future video,
05:33
you can also clone individual loads or copy them
05:37
by right clicking and selecting copy.
05:39
And then in your loads folder, you can right click and paste that load.
05:43
If you need to create a secondary load and simply make a new face selection.
05:47
For example, toggle off the target and select a new target.
05:51
Copying the load can be a great way to do this
05:54
for our purposes.
05:55
I'm going to right click and delete that bearing load,
05:57
keeping only the 90 degrees and the 45 degrees.
06:01
When we take a look in the solve area, we have what's called a precheck.
06:05
The precheck will let us know if we're missing any information.
06:09
If there is any potential information missing that might affect the results,
06:12
or if we are ready to solve
06:15
this icon will change colors throughout the process of setting up your simulation.
06:19
And once it turns green, you know that you have everything that's ready.
06:23
If it is orange, that doesn't mean that you can't solve your simulation study.
06:27
But it does mean that there could be a potential problem.
06:30
In our case, everything is good to go.
06:32
So let's make sure that we do save this design before we move on.
