  5. Upgrades to Improve System Foot Plate Analysis and Design Foot Plate Track Design Camera Structure Design

  6. Foot Plate Analysis and Design Criteria Current Design Proposed Designs Compilation

  7. Foot Plate Criteria Function: • Support weight of subject • 1000 lbs (500 lbs per plate) • Maintain similar performance to current • Deflection • Maximum Stress

  8. Boundary Conditions and Force Top 2.95 3.95 Bottom 1” diameter 0.75 from top 0.75 from side

  9. Current Foot Plate Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.375 in Density of 6061-T6: 0.0975 lb/in^3 Weight = 4.35 lbs Maximum Stress = 7,316 psi Maximum Deflection = 0.0185 in Boundary Conditions: UY = 0 in 3 corners, UX, UY, UZ = 0 in 1 corner Force: -125 lbs in 4 locations around center point Max deflection: 0.027 in Max stress: 3629 psi

  10. Foot Plate Designs Possible Design Change Avenues: • Thickness • Aluminum • Reduce to 0.25” from 0.375” • Material • Steel Alloy • Use thickness of 0.125” • Geometry • Drill out Hole Pattern • Mill out Material (through 0.25”) • Mill out Material (through all)

  11. Change Thickness Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.25 in Density of 6061-T6: 0.0975 lb/in^3 Weight = 2.90 lbs Maximum Stress = 15,861 psi Maximum Deflection = 0.0594 in

  12. Change Material: ASTM A36 Steel Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.125 in Density of ASTM A36: 0.28 lb/in^3 Weight = 4.21 lbs Maximum Stress = 60,327 psi Maximum Deflection = 0.1629 in

  13. Change Geometry: Drill out Holes Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.375 in Density of 6061-T6: 0.0975 lb/in^3 Weight = 4.15 lbs Maximum Stress = 8,377psi Maximum Deflection = 0.0199 in

  14. Change Geometry: Mill out Material (Through 0.25”) Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.375 in Density of 6061-T6: 0.0975 lb/in^3 Weight = 2.68 lbs Maximum Stress = 14,358psi Maximum Deflection = 0.0383 in

  15. Change Geometry: Mill out Material (Through All) Footprint Dimensions: 14.95 in x 7.95 in Thickness: 0.375 in Density of 6061-T6: 0.0975 lb/in^3 Weight = 1.85 lbs Maximum Stress = 24,305psi Maximum Deflection = 0.0753 in

  16. Analysis Comparison Moving Forward: 1. Optimize drill and mill designs, determine best configuration 2. Source pricing for each method 3. Make final decision on plate design

  17. Foot Plate Track Design Required Functions Enable West/East (W/E) Adjustment of Foot Plates. Allow User to Access Foot Plates Maintain Alignment of Foot Plates Proposed Concept

  18. Proposed Design • Allow W/E Adjustment • W/E track is perpendicular to the North/South (N/S) track. • W/E track enters side of foot plate base at height to allow base to sit on the ground to protect against vertical bending. • W/E movement is limited by width of foot plate base. • Two W/E tracks are used to protect against horizontally. • Will probably add less than 1 pound of additional weight. Unextended Fully Extended Note: Movement is limited by width of foot plate.

  19. Camera Structure Design Split into required functions Maintain Camera Orientation Maintain Orientation Layouts Maintain and adjust Camera Height Camera structure portability Maintain Camera Stability Camera Structure Selected Concepts Compilation

  20. Maintain Camera Orientation • Function: • Maintain Camera X and Y position from the footpad across multiple set ups. • Priorities: minimize human error, weight.

  21. Maintain Orientation Layouts • Function: Maintain proper camera locations • Priorities: minimize material (weight), aesthetics

  22. Maintain and Adjust Camera Height • Function: • Maintain and adjust Camera Z position • Priorities: minimize human error, weight.

  23. Camera Structure Portability • Function: • Allow for structure portability • Must disassemble into 61” x 48”x 8” carrying case • Priorities: minimize human error, weight.

  24. Maintain Camera Stability • Function: • Allow for Camera Stability • Priorities: Minimize Camera Movement, Minimize weight
