Fusion 360 Simulation (3D print)

1

Hey guys,
I am studying mechanical engineering and for my bachelor thesis I decided to build an electric longboard with as much use of 3d printing as possible.

This is the complete assembly.

Now I need your help, for my thesis I need some strength simulations. However, I am not sure how to calculate all the input data. I know how to simulate strength of the enclosure through deck deflection and bend of the motor mount through torque. I would also like to simulate strength of the locking ring using clamping force. Does anyone know how to calculate these forces?

Also, feel free to suggest any other possible simulations that I could do.

Thanks.

PS. You’re going to wish you didn’t ask :joy:

Vibration test on the mount and ring would be nice, that’s the most important forces the mount get

Torque tention on the mount too. Youd be surprised at how much our alu mounts twist when we gun it

Don’t forget that the climping is gonna slightly move your threads, possibly making the threads of the clamp not align with the holes of the mount itself.

You can simulate the bolts preload, and then add the motor loads as the following step. Make sure to account for friction. To cap up the preload force consider stressing the bolt to about 60% of the yield strength. This will be different for different bolts and you can find this info in tables.

I am not sure if Fusion has vibration simulation. Also not sure, where to get input values.

Your best bet is the multiple experts on the auto desk forum, I’ve seen very helpful responses on there including timespans which show in detail what you need to do.

Probably there are multiple threads waiting for you there which would bring you closer to the goal

Good luck

I got the mount already printed out and have about 100km on it, so far it works fine.

I did this simulation on a single mount, it bent couple of milimeters, however the two mounts are joined together with crossbar, which prevents any flex.

Wauv, this is my first time in this forum and look at the first question I found in here… Congrats and you are lucky to have such a project for the bachelor thesis… I wish mine was similar (I am an electrical & electronician though :slight_smile: I am using solidworks for cad and simulation, fusion 360 for cam the decks… Your topic is so important, shall we go on together on this ?
