Background A local trailer manufacturer is interested in implementing new solutions that would reduce or eliminate trailer sway (or "fishtailing”) in their product line. The company has hired your team as consultants to investigate new technologies or trailer designs to eliminate this problem. As an initial proof of concept, the company has asked your team to develop possible modifications to one particular popular trailer model. If successful, adaptation of your solution for other trailer models would be explored. Assignment Requirements For this project, you will analyze one or two promising technologies that are likely to improve or eliminate trailer sway. The baseline trailer you will be analyzing is an enclosed cargo trailer with the following specifications: Overall length (in) 195 Overall width including wheel wells (in) 93 Cargo box length (in) 148 Cargo box width (in) 69 Cargo box height (in) 73 Wheel position from hitch (in) 146 Wheel size (in) 15 Curb weight (lbf) 1225 Payload capacity (lbf) 1765 Assume that the vehicle towing the trailer is a 2017 Ford F150 SuperCab. Your proposed solution should be able to eliminate trailer sway up to speeds of 75 mph. Aside from the information above, the company did not specify any preferred method for approaching this problem. Assignment Requirements You should perform a system analysis of your baseline trailer with and without your proposed technology, and quantify the effect of your solution on trailer sway. Where applicable, drawings of your design are required. Include a CAD drawing in your report. Include calculations or estimates that relate to one or more topics from class such as equivalent mass/inertia, spring or damper elements, hydraulic or pneumatic components, electric motors, etc. Describe the impact that your proposed technology has on society. For example, will it create or eliminate jobs? Does it represent a significant hazard or nuisance to the community? Describe the impact that your proposed technology has on the environment. For example, will there be any change in pollution/emissions associated with its manufacturing? Analyze the economic feasibility of implementing your solution, including a cost estimate per unit once the technology has become mature.

Strategies TO ELIMINATE OR REDUCE TRAILER SWAY
Trailer influence, or fishtailing, is the point at which a trailer starts to move from sideto-side without anyone else, in the long run bringing about flipping and (in some cases)
turning the towing vehicle over, as well. It doesn't occur on vehicles with a fifth wheel
connection, for example, a verbalized truck, just on vehicles where the towing association
(hitch) is well behind the back pivot (Livington, 2011). The strategies to be applied include:
Grating Sway Control Bar
The advantage of a framework like this is minimal effort. T...
