Sinuous Wire Form Equations

[jkr4250]

Hey yall,

First post on this forum, i think im going to become a rather big fan of this place. So thanks again for taking the time for reading this.

Ok so basically my question is, my company is sort of diving into a new product that involves Sinuous wire forms (sine wave) the wire diameter varies but lets just say it is 0.125" diameter. and it's overall length is 36" long. I was wondering if there are any equations/formulas for putting load on the wire form axially and/or perpendicular to itself. right now we are just doing trial and error in order to hit our mark. So if there are please help.

Thanks again guys,

Jeff R.

From that generic a description, no "pure theory" will be more useful than simple tests. And, in fact, simple testing will be more useful at almost all levels.

You have (apparently) a "net" or maybe a weave of these unknown dia, unknown weave displacement and characteristics, unknown density of wires/area. That weave or net is suspended by unknown stiffness - probably around its circumference, maybe at only a few points. Once suspended, a load is imposed of unknown density, mass, unknown area/total area of the net, total size with respect tot he weave. At an unknown impact or dynamic.

So, what happens?

Don't know. Did you drop a cannonball into a hammock suspended at both ends by a between two palm trees? Or a ping pong ball into a window screen supported all the way around, or a bowling ball into a wire chickenwire mesh, or a dump truck mass of sand and gravel into a grading sieve ?
