1. Fifth Wheel Test Machine Project Concept Evaluation Group members: Jonathan Eckart Wayne Farley Rob Grace Chris Bozarth Academic advisor: Dr. Faryar Etesami

2. Preview Introduction Design Concepts Scoring Matrix Conclusion SIMPLEX 400 ® SOLID MOUNT FRAME SLIDING MOUNT

3. Introduction Fifth wheel – trailer to truck connection ConMet wants a machine to test ultimate strength of fifth wheels in axial direction Test machine must have: - Adjustable width and height for different models of fifth wheels - Data acquisition: need to know forces required to fail fifth wheel 300 kip

4. Rail Cart Concept Fifth wheel mounts to cart Kingpin is fixed Hydraulic cylinder pushes cart

5. Power Screw Concept Power screw load delivery Load cell measures force

6. Sliding Adjustment Concept Posts slide inside rect. tube Power screws adjust fifth wheel height Hydraulic cylinder pulls kingpin

7. Pulley System Concept

8. Plate and Screw Concept Screw adjusts width Pin placed through rail and plate Hydraulic jack adjusts height of platform

9. Cylinder Mount Concept Centerline adjustment with slotted plate Alternative form would allow vertical adjustment of cylinder

10. Pivot Arm Concept Arm with kingpin mounts to cylinder rod Arm can pivot away from fifth wheel assembly

11. Mechanical Advantage Concept Lever arm multiplies force of cylinder Vertical layout

12. SCORING MATRIX

13. Conclusion 7 different concepts No single concept itself will do the best job Final concept will use a combination of ideas from the concepts generated

14. General Concept 1. Hydraulic cylinder will be used to apply force to fifth wheel. 2. Slotted plate used for width adjustment 3. Hydraulic cylinder moves for height adjustment 4. Pivot points on ends of cylinder 5. Adapter plate for kingpin-cylinder connection

15. Hydraulic Cylinder LIFTING POINTS PIVOT POINTS 12” DIA BORE CYLINDER CAN DEVELOP >339000 LBS OF FORCE USING 3000 PSI PUMP
