Automated Marine Trailer Jack RYAN SCHECH ET 494 SPRING 2015 PROPOSAL PRESENTATION ADVISOR: DR. JUNKUN MA PROFESSOR: DR. KOUTSOUGERAS

Introduction to project Side mount ‘swivel’ design Eliminate manual operation Lift Capacity of 1,000 lbs. (commonly used marine jack rating)

Objectives  Design the housing of the motor, motor control, pulley assembly, rod, and gears.  Motor selection  Custom design a rod that will hold the small bevel gear and the pulley at fixed positions.  Large bevel gear with long threaded shaft and fixed plate containing a bearing  Pulley (find the available sizes on the market)  Motor sprocket (market)  Belt design (market)  Motor control (Arduino)  Power Source(12V power cord with standard 4-flat trailer wire plug that connects directly into your vehicles trailer light plug)

Deliverables  Overall design of an operational system  Designing the housing of the system  Analysis determining the sizes of the:  Motor  Pulley  Bevel gears  Threads  Stress analysis to determine the size of the rods  Modeling the characteristics involved on the rod in COMSOL  Developing a program (using Arduino) to control the motor  Modeling the Automated jack assembly in SolidWorks
