Design of Proposed Wind Turbine Tower Testing Facility at the University of Wyoming Original Design (Fall 2011): Wade Burkett Margaret KimblePresented by Margaret Kimble Meadow Ridley Senior Honors Project 2012
Presentation Outline Facility Overview and Background Faculty Requirements Design Concept Proposed Changes and Areas of Further Design
Facility Overview and Background
Background Future of Wind Power Taller Towers Different Composition Advantage of Taller Towers Minimization of Obstructions Composition Steel Lattice Post-tensioned Concrete
Overview Tower Testing Multi-Axial Testing Strength Fatigue Axial
Facility Requirements
Load Requirements Crucial Loads: Stop of Rotation Moment and Wind Stop of Rotation Moment Wind Loads Tower Facility
Load Application Locations of Applied Loads Mounting of Actuator
Axial Load Results from Equipment on Top Tower Self-weight Collar Design Applicable for Testing of Lower Segments Specific to the Tower being Tested Connect Directly to the Foundation Pad
Operational Limitations Testing Conditions Wind Speed Limitations 50 mph

Proposed Changes and Areas of Further Design
Proposed Changes and Areas for Further Design Strong Axis Design Inclusion of Buttress Full Height
Strong Axis Advantage Smaller Wall More Economic Disadvantage Limited Load Placement
Inclusion of Buttress Provides Stiffening for the Wall Allows for Greater Torsional Capacity Allows for Eccentric Loading
Full Height Testing Industrial Advantages Construction of Form Work Testing Advantages Reduction in Scaling
