Design Project Management Final Presentation Zachary Kirsch 15 November 2012

Project Motivation Industrial design student James Paulius Incorporating cycling and public transportation Need: To have additional accommodations for cyclists to store their bicycles while riding on public transportation buses

Project Description Design and implement a bicycle rack that can be mounted to the currently unused space on the rear of a commuter bus This rack can supplement the current rack mounted on the front of a bus This rack can be retrofitted onto currently running buses

Project Goals and Scope Proof of concept Rack deliverable (1) Arm unit Associated controls Mirror vision system Additional deliverable Mounting stand Testing All deliverables will be tested to demonstrate their proper functioning

Budget The budget request for completing this project will be $600

Desired Staffing Electrical Engineer (2) Communication Control panel Feedback systems Motor and power source sizing and selection Mechanical Engineer (2) Rack Mounting system Fatigue and stress analysis Material selection

Additional Support Faculty champion None Contacted Dr. W. Walter (ME) and Dr. F. Sahin (EE) Customer None Was informed that Mr. J. Schull would act as our customer He is unwilling to do so, but is willing to help establish a contact at RGRTA for this position

Feasibility Analysis Motor sizing Motor must be powerful enough to lift the arm with bicycle attached Suitable motor McMaster P/N 6470k72 1/17 hp. DC gearmotor Arm stress The stresses seen by the arm cannot exceed the arm material’s yield strength Suitable material McMaster P/N 8457k27 0.5” OD stainless steel tube
