  1. The CRUSHED Experiment By: Carlos Sanabria Justin Roose Phillip Munday

  2. The Experiment • We are to apply a quasi-hydrostatic pressure on a 6” diameter pipe. Figure 1 – Sketch Pipe under hydrostatic pressure

  3. The Design Process Hydrostatic Press Outer Ring Pipe Spacing (incompressible media) Figure 2 – Transverse cross section of the pipe being compressed by six sections

  4. Final Design (Fall) Design for a surface pressure up to 10,000 psi Figure 3 – Final Design for the fall semester

  5. The problem: • The strongest actuators that can accommodate our budget are not nearly as strong as our calculations assumed • Our sponsor advised that we should design around the actuator’s force

  6. Available actuators considering our budget Figure 4 – Model Number RW50 Figure 5 – Model Number RW51

  7. Actuator Dimensions 5.35 in 2.25 in 4.85 in 1.63 in 4.34 in 1.94 in Figure 6 – RW50 Dimensions Figure 7 – RW51 Dimensions

  8. New Ring Dimensions 14.05 in 19.68 in Figure 8 – Ring Dimensions using RW50 Figure 9 – Ring Dimensions using RW51

  9. New System… What next? Replacing Actuators New I-Beam Dimensions Natural Rubber Insertion Figure 10 – New System Layout and next steps

  10. I - beams w s h t

  11. I - beams 12.73 in w δ s h 8.11 in t Figure 11 – Ring Piece Dimensions and Deflection

  12. I - beams NOT SIGNIFICANT!

  13. I - beams 2.796 in 4 in 0.326 in 0.293 in Figure 12 – I - beam dimensions

  14. Natural Rubber Insertion Dimensions have been recalculated with a rubber layer of 1/8” Natural Rubber Insertion Figure 13 – A close up view of the natural rubber insertion

  15. Replacing Actuators by Stationary Columns L = Length of the Column Columns are characterized by it’s Slenderness Ratio K = Radius of Gyration

  16. Replacing Actuators by Stationary Columns • If the Slenderness Ratio < 10 • The column is now bound by the Mechanical Properties • To ensure this: • L = 1.94 inch • same length as hydraulic cylinders • Diameter > 0.776 inch • Diameter is set to be 1 inch • Made out of structural steel ASTM - A36 • Same as I-beams

  17. Replacing Actuators by Stationary Columns Stress = 12 ksi Strain = 0.0004

  18. Final System New I-Beam Dimensions Columns Natural Rubber Insertion Figure 14 – Final System

  19. Some Drawings(Sections) 2.4 in 2 in 3.05 in 3 in Figure 15 – Section Drawing

  20. Cylinders Columns 1.9 in 1.9 in Figure 17 – Column Drawing Figure 16 – Cylinder Drawing
