compression gaskets

[stefanoma]

hi friends designers,
I have to understand how deform a seal of which I have the hardness in sh and the surface. would someone be able to say by applying a force with a pneumatic cylinder a method of calculation in order to know the deformation of the seal itself i.e. how much compresses? Does it behave like a spring with a constant elasticity? thanks to all for the interest and good work. steak

I don't know, but I think you don't need shore hardness which is a parameter that represents penetration resistance, not deformation.

It should be seen that form has the seal to be able to understand if possible to try to make an analytical calculation ... but I think in the end a fem made well is the most reliable method

you can treat it through the beam theory, even if beam is not, if you need an indicative calculation.[math]\delta =\frac{fh}{ea}[/math]where f is the etched force; h the height of the seal; and the module of young and to the area.
Moreover, for the calculation of bolted elements, the rigidity of the seals is used by:[math]r =\frac{ea}{l}[/math]

Thank you so much!! !
