@Levendis - yes, we will mix it up, but a little later. Just keeping things simple at this stage. Ultimately, whilst it seems that I am running a study group, the intent is to ensure the Kraken frame design fundamentals are fully understood. There are far more qualified people than I and it would be quite embarrassing to overstretch my simplistic knowledge.
The street art has become very popular around Perth and Fremantle. My favourite remains the the giant numbat. https://www.google.com.au/search?q=s...MQsAQILA&dpr=1 @thanks webbah and jlk - appreciate the interest |

Reason: Further Analysis of Arm Stress
|
|
|
|
Say the arm is 3mm thick total and the top and bottom parts that take most the stress (the green shaded areas in the pic) are say 0.5mm thick.
If the arm was 4mm, are the stressed layers (green shaded areas) still 0.5mm thick or do the stressed layers also increase in thickness? Being carbon fibre... I have seen this before where you see the top or bottom "sheets" of the CF cracked and the middle just bent and/or delaminated. Definitely seems true that the top and bottom takes the most force.... thinking about it that true of any layered structure, which of course that's all CF is... as the epoxy resin is just a filler really.... Seems like there's a lot of carbon in there we are weighing down our quads with which is doing not much! |

The street art links are awesome. Thanks.
It would seem the takeaways from the diagrams are: 1. Quad arms should be feathered for optimised strength to weight ratios for arms. 2. The same arm is not 33% stronger when it is thickened from 3mm to 4mm [crickets...] For those who have destroyed more than a few quads we would also know from experience that the weak points are at the bottom plate (typically thinner in a non-unibody quad), the arm mounting screws and screwholes. And that the analysis should also take into account forces acting in the longitudinal axis in addition to the pitch axis. It would be great if your solid works elves could formalise that study! (i.e. optimum at three attachment M4 screws with washers and bottom plate that can be 50% as thick as the arms provided that there is a carbon finer brace?) Were those nylon screws on the old Blackout miniH a good idea after all? |
