Practice exercise

00:01

This is a practice exercise video solution.

00:06

For this practice exercise, we're going be carrying on with our conveyor drive design.

00:12

If you haven't solved the simulation study then make sure that you do solve study 1,

00:16

and we'll begin by selecting study 1 right clicking and cloning the study.

00:22

Study 2 that gets cloned we want to go in and modify our materials so make sure that study 2 is active.

00:28

Go to the study materials and we'll be changing this back to a steel material.

00:34

You can use same as model to use the default steel or you can pick another steel material.

00:40

From here we now want to solve simulation study 2.

00:44

Again, we still have a warning for the simulation study because of those under-constrained elements in the original electric motor,

00:51

but that's going to be okay.

00:52

We'll simply solve and compare the results.

00:56

Now that we have the results, let's take a look.

00:60

Once again, the factor of safety is 15, which means that it's well above our target.

01:04

But let's use our Compare option and let's take a look at study number 1 on the left and study number 2 on the right.

01:13

We can see that the safety factor is fine and we want to make sure that we do synchronize the results type,

01:19

so that way we are looking at stress, strain as well as displacement on both.

01:25

We can see that on the right the steel material actually has a slightly higher value,

01:30

but once again these are well below anything that this material would see and cause a failure.

01:36

You can see that in first and third principal stresses.

01:39

Once again, they're very similar results.

01:41

However when we get to our displacement, we can see that the aluminum material has 0.126 mm of displacement and the steel material is 0.045.

01:53

This is a much smaller displacement.

01:57

And if we were to take a look at this displacement,

01:60

once we finish compare and go to our results and set the deformation to actual, we can see here that the actual deformation is relatively minimal.

02:10

Even when we take a look at study 2 and we're looking at the deformation, we're looking at a relatively small amount of deformation.

02:17

However, the difference between 0.125 and 0.045 is quite drastic.

02:23

So in this case the steel material might be a better choice depending what our requirements are for our conveyor system.

02:30

There are additional changes that we could make to this bracket and continue to explore,

02:34

but at this point, make sure that we do save the design before moving on.
