Re-solve a simulation.
00:06
In this video, we'll solve a simulation study and we'll compare simulation results.
00:12
In Fusion 360, we want to carry on with our motorcycle rear set.
00:16
At this point, we have a new simulation model and study that needs to be solved that has multiple load cases.
00:22
We also have a copied or cloned study inside of our frame mount only that needs to be solved as well.
00:28
When we go to solve, all of these will be displayed in the solve dialogue allowing us to see what studies need to be solved.
00:35
In this case frame mount mod study 1 static stress and frame mount only study 2.
00:42
It's important to note here that I am solving on the cloud so I can't solve both at the same time,
00:47
and the fact that our frame mount mod has 2 load cases doesn't come into play when we're talking about using cloud credits for our solve.
00:55
It's only when we need to solve additional studies reviewing different materials or entirely new simulation models.
01:02
From here I'm going to solve both of these studies on the cloud and I'm going to take a look at the results as soon as they're calculated.
01:09
Now that we have our results solved, we can see here that the safety factor in this case we're looking at frame mount mod for load case 2 is 1.392.
01:19
If we take a look at load case 1, it's 1.44.
01:23
So these different load cases help us better identify and understand the differences between the upper and lower bolt positions.
01:31
But let's use the compare tool to take a look at the results between the original setup and the modified design.
01:38
When we use compare, we can pick up to four different views.
01:42
In the upper left, I want to make sure that I select in this case frame mount only.
01:48
In this case, we have static stress study 1.
01:52
This was the original design.
01:54
In the upper right, I'm going to select frame mount only study 2, this is where we used our 7075.
02:01
In the bottom left I'm going to select frame mount mod static stress,
02:06
and in the bottom right, I'm not really concerned with any of the other options,
02:11
but I'll select our frame mount mod, in this case I'll use load case 2.
02:18
I want to make sure that all of these results types are synchronized.
02:21
So that way I have an equal playing field in terms of looking at stress distribution or safety factor,
02:27
and then I can take a look at the safety factor for all four.
02:31
In the upper left, we're taking a look at the frame mount only study one.
02:35
This was the original design with the factor of safety of 1.087.
02:40
In the upper right, we're taking a look at the study 2 which was the change of material to 7075.
02:46
You can see that this resulted in a lower factor of safety.
02:50
Now while we change to what's typically called more structural aluminum,
02:54
its properties are not good for this type of part and the way that it's being loaded.
02:59
In the bottom left, you can see here that we're looking at our frame mount mod study one and load case one.
03:06
And this was a 1.44.
03:08
This had the load applied to the upper two bolt holes or the upper foot peg location,
03:14
and lastly in the bottom right, we're looking at load case 2 of the same study.
03:18
You can see here that the factor of safety is slightly lower.
03:21
But what's important to note is that the geometry changes whether or not the loading position is in the upper or lower holes,
03:29
the factor of safety has increased with our geometry changes.
03:33
We could likely go back to the drawing board and consider using a steel material and something that's quite a bit thinner,
03:39
maybe a cast steel and that could likely produce much better results without having to greatly increase the thickness or change the geometry.
03:48
But at this point, it's a great exercise to continue to modify the bracket.
03:53
Maybe change the material or change the geometry see if we can increase the factor of safety to above 2.0,
04:00
making sure that we have enough margin of error for the amount of load that's going to be applied.
04:05
Once again, we used a 350 pound load applied to the end of the foot peg,
04:11
and this would represent somebody putting all of their weight on one side of the bracket.
04:16
And that's really not realistic.
04:18
But it does account for things like jumping and landing in those increased loading situations that you might see.
04:25
So at this point, I'm pretty happy with the results.
04:28
I would continue to make adjustments by cloning the simulation model, making additional changes,
04:33
or cloning the study and exploring some more materials.
04:36
But we want to make sure at all times that we try to preserve the original results so we can always go back to them,
04:43
whether that means cloning a study and looking at different loads or cloning the simulation model altogether.
04:49
From here, we do want to make sure that we save all the results that we've created, keeping in mind that these results are stored on the cloud.
04:56
So anytime you open this design, even if it's from another computer, those results will be available.
05:02
But once it's saved, you can go ahead and move on to the next steps, taking a look at practices and challenges that are associated with the course.
