Hi guys,
Through a local DOD contractor I found a few small shops that will make Berillium Diaphrams... Apparently the new fighter jets use alot of the material, so they are set up to work with it, and do small runs... So , what I need, to get a price, is CAD drawings of the diaphram, and the piece that gets pressed into the middle.. I have been told that they can do it, based upon my description. So, did anyone ever make a drawing of the diaphram...or maybe please......mike...could you... Rich |

It's an effin spring...
So you need: 1. Material- 2. Material Thickness- makes a big difference on rate 3. Similar diaphragm dimensions 4. Heat treat for durability-forming issues. For a quick and dirty material properties calc, cut a strip, measure the width, and thickness. Clamp in a vise and Measure the distance from the wall to the point where the force will be applied. Add weight or force and measure the deflection. Calculate the modulus of elasticity and look up material. Use the cantilever deflection equation to calculate the modulus... deflection= load*length^3 (cubed)/ 3* modulus* width *(height^3 (cubed)/12) There ya go... Won't be exact but I bet it will get you within 85% of the correct value. |
