Modeling in SolidWorks
Induction Model
The team theorized that Magnetic Induction could be utilized to generate the desired power specification. Moving a coil of wire around a magnet (or vice versa) pushes the electrons in the wire to create an electrical current. The drivers are suspended in the center of magnetic sheets with coils on either end. A suspended design such as this allows for more degrees of freedom, which may potentially lead to greater opportunity for power generation. The model itself was made out of a combination of SolidWorks part files downloaded from McMaster-Carr, as well as some parts created in-house that may be produced in the University’s machine shop.
Alternator Model
This model is a slightly more practical design which includes power being harnessed and converted through the use of an alternator. With the drivers constrained to one degree of freedom, energy can be converted from linear to rotational motion through the use of a rack and pinion gear system. The racks will be fixed vertically to either side of the driver. As the water current pushes the drivers up and down the rack will rotate the pinion thus spinning the alternator. This design can be modularized with each unit consisting of 2 drivers and 4 alternators, additional units may be added to produce the desired amount of power. The next step in modeling is to enclose the alternators and battery pack in a water tight compartment.
