Terminology research...
Jan. 10th, 2011 08:02 amThe 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:
Cheers...

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...
