    pressure reservoir needed

    I am going to use a 40mm bore short stroke double acting cylinder at high speeds. I would use an air mainline in a lab at 6 bar .. or alternatively a portable compressor. Someone told me that I might need a reservoir between the 5/2 valve and the mainline/compressor. Do I? I would have though a...

    Pneumatic components for double acting cylinder 'gun'

    Hm I had thought about a spring system, usually they are contained within a single acting cylinder. However, searching through the catalogues there are no cylinders that are compact enough that give quite high forces ~1kN, i guess it's because they're acting against a spring... Mmm, I'm not...

    Pneumatic components for double acting cylinder 'gun'

    Hello. I am looking to create an pneumatic cylinder actuated system that extend the cylinder at high speed when a trigger is pressed, and automatically returns to position once the stroke is completed. I was thinking of having a 4way trigger valve, and a air chamber connected to a compressor...

    estimation of winkler foundation modulus

    Thanks for the information and the links. Indeed the element in consideration was a rod rather than a slab, so probably the equation above is not applicable. Thank you, eponalank

    estimation of winkler foundation modulus

    thread256-151955 Hello. There was this thread that gave a very simple formula for estimation of winkler foundation modulus as "K = E*(1/B+1/L+1/h)". K : Winkler modulus [kN/m3] E : average Young modulus of the soil [kN/m2] B : width of the strip [m] L : length of the strip [m] h : limit depth...
