  2. Problem Statement • Trucks accumulate large amounts of snow and ice, causing severe safety concerns for all drivers.

  3. Justification • There are an estimated 15.5 million trucks operating in the U.S., of which 2 million are tractor trailers Source: Trucking Statistics Source: Clip Art

  4. Justification • Flying ice from tractor trailers has been documented to cause serious safety issues Source: Ramirez, M.

  5. Justification • Benefits of removing ice and snow: • Improved visibility • Prevents injury or property damage • Prevents laws and fines • Improved fuel economy • Reduce insurance claims & law suits • Meet OSHA regulations for truck drivers Source: Trego, T. Source: www.wfmz.com/news/22522041/detail.html

  6. Justification • The build-up of snow and ice on top of a tractor trailer can significantly increase the height and weight of the truck, causing major problems • http://www.wpxi.com/video/22584092/ Source: Snow, ice make tractor-trailers over weight.

  18. Numerical Analysis Surface Area of Trailer = 58752 in2 Trailer length = 48 ft = 576 in Trailer width = 102 in Area = Length X Width = 576 in X 102 in = 58752 in2 Specific weight of water @ 32 F = 0.04 62.42 X = 0.04 Volume of water equivalent on trailer = Surface area of trailer X Height of water = 58752 in2 X 1.2 in = 70503 in3 Weight of water to lift = Specific weight of water X Volume of water on trailer = 0.04 X 70503 in3 = 2821 lb. Pressure Required = Weight of water to be lifted = = 0.05 or psi Surface area of trailer For a safety factor of 2 (designed to lift two times as much snow as we feel necessary) = 0.1psi

  29. Results

  30. Ideas for Concept/Testing Revision • Adjust the shape of the inflatable • Inflate chamber down the middle first • Include a rigid structure down the middle • Use a stronger material • Thicker plastic • Pulsating air supply • Could be accomplished through valves or computer control • Conduct testing in a cold environment (below freezing) • Walk-in freezer • Teflon coating • Use Scotchgard instead of cooking spray

  31. Refined Design

  32. Actual Product Ideas • Proposed material - nylon coated polyurethane • Waterproof and airtight • UV and chemical resistant • Puncture and tear resistant • Workable and pliable in cold temperatures • R/F and chemically bonded for strength • Smooth, slippery surface • Can be custom cut to fit any pattern • Inflated by air compressor already on truck Source: http://www.wing.com/wing-materials-construction.php
