  1. Department of Mechanical Engineering Villanova University Telescoping Wheelchair Ramp Frank Genova – Team Leader Daniel Peters Anthony Rossi Dean Perdikakis

  2. Telescoping Wheelchair RampIntroduction: • Difficulties in today’s society for handicapped individuals. • Ramps on the market not efficient in many cases. • Maneuver, Ease of Use, Weight Reduction

  3. Telescoping Wheelchair RampBackground state of the art: • Research, 2-3 step vertical rise (24”). • ADA requirements: • Power Wheelchair • ADA adjustments

  4. Telescoping Wheelchair RampBackground state of the art: • Separate Runners • Weight Reduction (PRO) -Aluminum Design • Set-up, Maneuverability, Transportation (CON)

  5. Telescoping Wheelchair RampBackground state of the art: • Roll up Ramp • Weight Reduction (PRO) -Aluminum Design. • Wide 30” Surface (PRO) • Structural Integrity (CON) -Max 5’ Length

  6. Telescoping Wheelchair RampBackground state of the art: • Full Width Ramp • Only Van Design Exists • Extends up to 8’ (PRO) • 30” driving surface (PRO) • Ramp weighs 65 lbs (CON) • Cumbersome telescoping system (CON)

  14. Telescoping Wheelchair RampComposites: • Composite design • Information received through Dr. Brian Sullivan, specializing in composites. • Model as simply supported (max. deflection in center, max. moments at fixed ends). • Transverse, uniaxial loading • Carbon fiber reinforced epoxy (E = 3.4E+6). • 0/45/90/-45 Layup Layup

  15. Telescoping Wheelchair RampStatement of Work and Design: • Spring Loaded Pin System chosen • Interlocking aluminum guide rails on one side • Ramp adjustable to any length • 360° wheels on underside for ease of opening • Composite Panels • Rubber non-slip surface • Rubber Ends
