  1. Team Fuzzy Balls Waqas Abbasi Dusty Ashberry Daniel Grant Chadwick Harris Gene Karshenboym Robert Ricaud

  2. Presentation Overview • Finished Layout Drawings • Engineering Analysis • Force Analysis • Deflection Analysis • Required Clamping Force • Buckle Tensile Strength • Tolerances and Cart Force Analysis • Weight and Dimensions • Material Selection Analysis

  3. Finished Layout Drawings New layout drawings with air compressor and latches

  4. Engineering Analysis • Force Analysis Total Force Calculations

  5. Engineering Analysis Cont. • Deflection Analysis

  6. for deflection in the center lines of all lips, this is unacceptably high change quantity of supports from 4 supports to 8 supports Engineering Analysis Cont. • Deflection Analysis Cont.

  7. Engineering Analysis Cont. • Clamping Force

  8. Engineering Analysis Cont. • Buckle Tensile Strength • Total tensile strength must be greater than 600 lb. Assume using steel as the buckle material with a UTS of 120000 psi. • With a safety factor of 2 , d=.08 in

  9. Engineering Analysis Cont. • Buckle Tensile Strength Cont. Use 1/8” diameter rods for the buckles, this will give 1473 lbs of force per side, this yields a total force of 2945 lb.N . Areas of ConcernSolutions -Where the buckle meets the plastic -Expand Contact Area of Buckler -Deflection of the lid. -Brace Lid - Bowing of the sides of the container -Brace sides or choose different materials

  10. Engineering Analysis Cont. • Tolerances • Around the seal, 1/32” • Elsewhere on the box, 1/8” • The cart tolerances are ¼” • Cart Analysis • Cart Load Analysis • F = 28 lbs • F/4 = 7 lbs • Compressive force on all four legs is 7 lbs

  11. Engineering Analysis Cont. • Weight and Dimensions H x W x DWeight -18” x 18” x 18”, Container -18 lbs for box -6” x 6” x 18” , Compressor -10 lbs for compressor -30” x 30” x 20”, Cart -30 lbs for Cart

  12. Engineering Analysis Cont. • Material Selection Analysis CES Software of Price/Density vs. Young’s Modulus (stiffness)/ Density

  13. Engineering Analysis Cont. • Material Selection Analysis Cont. CES software of the Tensile Strength vs. price for the latches of the buckles

  14. Deliverables • Next Week • Part Drawings • Ongoing • Website Maintenance
