Project Review • Capstone Team • Andre Nylund • Chris Grewell • Craig Lechtenberg • Fadel Al Jutail • Matt Melius • Mufeed Yacoub • Team Advisor • Dr. Raul Bayoán Cal • Customer • Daimler Trucks North America
Project Review Tunnel Details • 12,000 sq. ft. facility • Wind speeds up to 65 mph • 30ft long test section 21ft wide 26ft tall
Project Review • Pressure sensitive floor for calculating trucks drag coefficient. • Smoke wand for flow visualization Tunnel Details • Rotating floor panel to test various angles of attack
Project Review Mission Statement: Improve smoke testing methods • Increase the testable area within the wind tunnel • Increase stability of the system • Deliver smoke to location of interest accurately • Provide these requirements while maintaining negligible aerodynamic impact to test region • Delivery of final product by June,16th
General Scope Modification Modified Scope • Design Complete System • Build Roller Box Original Scope • Design Complete System • Build Complete System
Concept Design Wand Support Rollers Drive Motor Wind Tunnel Wall Horizontal motion Vertical motion Tunnel seal Vertical Rails Vertical Carriages Smoke Wand Horizontal Rail Horizontal Carriage
Horizontal motion Roller box Allows the smoke wand to move in and out of the tunnel while being supported Linear actuator Pre-fabricated
Vertical motion • Trolley • Designed with simple fabrication and installation in mind • Lifting motor • Drive system • 700 lb/in • 10 ft/min • 1.5 hp • Ball screws • 1” X 0.5” (OD X Pitch) • 21’ Long
Tunnel seal Rolling shutters • Custom fit shutters to prevent pressure from escaping from the wind tunnel
Roller box components • Flat Roller Beam (2X) • Angular Roller Beam (2X) • Rubber Roller Wheel (16X) • Roller Housing • Roller Clamps-Upper and Lower Roller Box
Stability • Four sets of rollers • Sixteen points of contact Roller Box • Adjustability • Two adjustable set screws/roller assembly • Angel variation • Upper and lower brackets are loosened to rotate
Final Design Progress • Horizontal motion (completion 6/6/2012) • Linear actuator • Roller box (65% complete fabrication) • Vertical motion (completion 5/30/2012) • Trolley • Lifting motor (70% complete design) • Tunnel seal (completion 5/30/2012) • Rolling shutters (70% complete design)
