  1. Ryan Bean John Hieb Will McCoy Devon Norman

  2. Contents Length Motion Motors Drive Assembly Length Rail System Platform Design Width & Depth Motion Data Acquisition Data Transfer

  3. Length Motion Motors Motor Options 1. Series Motor with Brushes 2. Brushless DC Servo Motor 3. Brushless AC Servo Motor

  4. Series Motor with Brushes Advantages + Lower cost Move platform quickly Disadvantages - Less dependable (Brush failure) Difficult to control Linear encoder needed to determine position

  5. Brushless DC Motor Advantages + High starting torque Closed loop control Smooth operation High resolution Disadvantages - Made for large scale applications Expensive power supply More costly than conventional motors

  6. Brushless AC Servo Motor Advantages + -High starting torque -High resolution -Smooth operation -Highly recommended for similar applications -Easily controlled Disadvantages - -High Cost

  7. Drive Assembly Rack and Pinion Advantages + Low Profile Safety Low Cost Dependable Disadvantages - Binding & torque considerations

  8. Length Rail System Rail Options 1. Angle Aluminum 2. DualVee Linear Systems 3. Shaft and Rollers

  9. Aluminum Angle Advantages + Low Cost Easy to Install Disadvantages - No Vertical Constraint Dependent Upon Flume Rail Straightness

  10. DualVee Advantages + Vertical & Horizontal Constraint Independent of Flume Rail Package Deal Disadvantages - Complicated Installation High Cost

  11. Shaft and Rollers Advantages + Vertical and Horizontal Constraint Same Performance, Lower Cost Independent of Flume Rail Disadvantages - Some In-House Manufacturing

  12. Platform Design Constraints: Mounting Area Proximity of Water Accident Safeguards Easy Mounting & Removal Cantilevering Concerns Square Tube Concepts: Planar Design Hook Design Gantry Style

  13. Planar Design Hook Design Platform Design Support Rail Style Support Rail Style (T-channel)

  14. Gantry Style Support Rail Style (C-channel) Platform Design Features: Platform Elevated from Water Motor & Shaft Easily Accessible Restrained Vertically & Horizontally Easily Mounted & Removed from Flume Sides Guards Prevent Accidental Injury (Plexi-glass Window)

  15. Width & Depth Motion Advantages • High Accuracy • Preassembled • Motor Control Package • Easy Installation (plug & play) • Optional Way-Covers Disadvantages • Slow Travel Velmex Slides

  16. Velmex Slides Mounted Downstream Equipment: 80” Powered Slide (blue) 80” Free Slide (orange) 50” Powered Slide (green) 50” Way-Cover (NS) 90o Gusset (red)

  17. Data Acquisition Three Potential Methods: Computer mounted on platform with separate Data Acquisition unit Data Acquisition computer Data Acquisition cards in a computer Computer: A PC running windows XP

  18. PC and DAQ • Advantages + • Easy to upgrade • Standard operating system • User friendly • Disadvantages - • Requires the most space • Unnecessary features

  19. PC Data Acq. Unit • Advantages + • Standardized add-ons • Requires little space on platform • Disadvantages - • Expensive • Unnecessary features

  20. PC and PCI DAQ Cards • Advantages + • Least expensive solution • Sensory equipment can interface with PC • Disadvantages - • Not compatible with high speed data acquisition components • Unnecessary features

  21. Data Transfer: Wireless Advantages + • Transmits data the necessary distance • Simple to implement • Disadvantages- • Slow data transfer • Security issues

  22. Flume Mockup Modular System Flume: 5 pieces Wedge: 1 piece Features Testing 0o Incline Testing 10o Incline Disassembly for Easy Transport
