Design of a Triplate
Design of a Triplate
(OP)
We had to double check the calculation made by a chinese engineering team and we figured out almost everything except the formula at row 34. Can anybody help? https://i.imgur.com/aJpB75K.jpg
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Design of a Triplate
(T/dB)(R2+r2)/(R2-r2) = kT/dB
where r is the radius of the pin.
With R = 350mm and r = 92.5mm, k = 1.15
So σ3 = 1.15T/dB
Not sure that is much help. Doesn't make a lot of sense to me.

(R^2+r^2)/(R^2-r^2) = k ?

Didn't have my calculator handy... It looked like the k value wasn't in keeping with the R values...

RE: Design of a Triplate
R = 350; d = 185, so r = 92.5
k = (3502 + 92.52)/(3502 - 92.52) = 1.15 (looks okay)
An equivalent expression is: k = (Aoc+Ap)/(Aoc-Ap)
where Aoc is the area of the outer circle and Ap is the area of the pin.

I am not sure that Table 13.5 is appropriate to the actual loading conditions, but I do not have a clear picture of a "triplate" or how exactly it is used. The diagram is not clear.
