These must be sliding bogies. However, I cannot remember now the proper terms for disteso/non disteso. It should be rearward/forward but am not sure.
EleoE Apr 22, 2012:
Tom, it's the kind of chassis.

cmq disteso/distesi è riferito a telaio/telai
Tom in London (asker) Apr 22, 2012:
Yes Yes, I saw that website myself. So in your opinion, what is the meaning of "disteso/non disteso" (it may have nothing to do with bench testing).
EleoE Apr 22, 2012:
Because there is only one way to position the bogie on the bench. Here they are talking about the way the bogie is: disteso/non disteso.

Tom in London (asker) Apr 22, 2012:
Why not? Why not? What would you suggest? Are you an expert in this field?
EleoE Apr 22, 2012:
I don't thik so. :)
Tom in London (asker) Apr 22, 2012:
I think--- --- they may be talking about how the bogie is positioned on the test bench. But I'd appreciate an expert opinion.
EleoE Apr 22, 2012:
They could be talking about variable gauge bogies.
Tom in London (asker) Apr 22, 2012:
Nothing to do with ships -it's about train bogies. Sorry folks, I didn't choose "shipping" as the category -Proz did . My question is not about ships - it's about train bogies.

(non) stress-relieved

Dal link sottostante:

Per determinare i carichi affaticanti durante le prove di fatica, si distinguono i seguenti casi:


· per telai carrello non stress-relieved (ossia non soggetti a ricottura di distensione), il valore


limite di ampiezza di tensione dinamica ammessa 2sAlim=smax-smin è indipendente dal valore di
smean. I valori di ampiezza dinamica ammessi 2sAlim dipendono dalle categorie di intaglio
definiti in Appendice C al rapporto e valgono, per acciai con carico di rottura minimo di
420 N/mm2, 240 N/mm2 per il caso A (materiale base o saldatura di testa fresata), 158 N/mm2
per il caso B (saldatura di testa), 132 N/mm2 per il caso C (saldatura di testa con variazione di
momento di inerzia, ad angolari o piastre di testa), 82 N/mm2 per il caso D (fillet weld,
saldatura a coprigiunto), 50 N/mm2 per il caso E (projection weld, fazzoletti o pioli per
collaborazione);

disteso/non disteso

I know these links are referring to model trains, but who knows....?

The bogie stretcher on the main chassis was now machined and hole drilled and reamed to size.

Whilst all parts had been machined correctly the bogie stretched was 3/16" out of position all due to misunderstanding the plan

The centre bogie stretched tried on the centre piece to check for size.
Note from asker:
The English is terrible here - I assume this is a translation from German to English. But thanks for the reference.
