Presentation 2 and Updates April 8, 2020

The team returned from spring break refreshed and ready for more work on the wayside project. We are improving our designs by adding wider t-slots, a more compact linear actuator, and track rollers for the third rail to ramp on and off. We got to show off our design work in presentation #2 click the link to view ==>(Presentation 2).

In the presentation, we discussed our specifications, the mechanical and electrical final designs. We also included what still needs to be done which includes designing safety guard rails and some final hardware. The team wanted to draw the electrical components and integrate all the wiring however, that will be too difficult under the time constraints so we have decided to only include electrical schematics. We do plan to include some assembly animations that show the bogie traveling down the rail to highlight how the conductor shoe contacts the third rail. Our presentation also included FEA on the bracket for that holds the conductor shoe mechanism and the track. The team is using a BoM for purchased materials and for needed materials if next year's team needs the information to build the design. We are under our allotted budget of $1000 by $58.81 in regards to what the team purchased already.
