Terminology research...

The only thing worse than coming across a Russian word that, according to Google, does not exist outside of my document is a word that is used some number of times, but never on a page that might provide an English equivalent. In the first case, I'm simply well and truly Sierra-Oscar-Lima; in the latter, I need to actually do some work.

So it was yesterday with the word "заневолевание," a term applied to springs. From the context, it was clear the term referred to some operation performed on springs.

My first promising lead was a Russian patent involving a device to perform this operation on springs, but it led nowhere. Then, I was fortunate enough to run across a Russian site that explained what happens during the process. My partial translation:

The process of fabricating heavy-duty springs should end with a production test or "заволеванием," which consists in compressing compression springs until the coils touch each other [...]. During "заневолевании," springs are subjected to loads that exceed the elastic limit, which causes the springs to plastically deform, creating residual stresses that are opposite in sign to the working stress. This allows the spring working load to be increased during operation.

I then did the following Google search:

spring load complete compression "plastic deformation" "residual stress"

which led me presently to a "Google Books" page in a tome titled Space Vehicle Mechanisms: Elements of Successful Design, wherein I found the following:

Helical compression springs are frequently coiled such that when they are compressed to a solid the first time, significant plastic deformation and set occurs. The resulting residual stress pattern will be opposite to subsequent applied stresses and further set during use will be minimized. Often, this "set-out" procedure is conducted at elevated temperature [...].

I'd have felt better if the Web provided some corroborating use of this kind, but nothing appears on the first couple of Google pages. In the end, this result seems a lot more solid than most, so I'll run with it.

Cheers...

Wow, thanks for this. All the strange words I have encountered today were at least in English and I could figure out what they meant.

For example I was in a meeting where someone kept asking if an invigilator would be necessary for the staffing plan of a workshop with a test at the end.

I honestly think from the discussion that followed some people thought he was talking about a defibrilator.

Это опечатка. Правильно "заневоливание". http://www.metiz-krepej.ru/prujina/Zanevolivanie-pruzhin.html

По-английски prestressing

Sounds better than "set out." ;^)

(Unless there are many ways to prestress a spring, and заневолевание is just one of them.)

Alas, the typo was my fault. Indeed, the term I was hunting was "заневоливание."
