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
Tunnel Details Pressure sensitive floor for calculating trucks drag coefficient.
Smoke wand for flow visualization
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

Final Detailed Design
Horizontal motionLinear actuator • Pre-fabricated
Roller box• Allows the smoke wand to move in
and out of the tunnel while being supported
Vertical motion
Lifting motor• Drive system
• 700 lb/in • 10 ft/min• 1.5 hp
• Ball screws• 1” X 0.5” (OD X Pitch)• 21’ Long
Trolley• Designed with simple
fabrication and installation in mind
Tunnel sealRolling shutters • Custom fit shutters to prevent pressure
from escaping from the wind tunnel
Roller Box• Roller box components– Flat Roller Beam (2X)– Angular Roller Beam (2X)– Rubber Roller Wheel (16X)– Roller Housing– Roller Clamps-Upper and Lower
Roller Box
Roller Box• Stability– Four sets of rollers– Sixteen points of contact
• 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)
