Week 3 progress

During week 3, after our design presentations, my team and I were able to fabricate column supports for the track. Also, I help my team cutting plywood mold to make the curve track. The idea was to kerf the wooden track, add wooden clue to the slits, clamped on to the arc-shaped mold, and leave it overnight to dry.

Since I am planning to fabricate the guide rail, I emailed Dan about kerf specifications for the angle iron. I am planning to use 3/16'' thickness 2'' x 2''x 6 ft 3 pieces and 2'' x 2'' x 3 ft 1 piece of angle iron to fabricate the guide rail.  Dan emailed me back saying that each slit has to be 4-6'' apart and depth of each slit has to be about 3/4'', and also to use an acetylene torch to help the angle iron to bend. I am planning to get the guide rail done the beginning of next week.

On Thursday, I helped Eric to buy wood and fasteners from Home Depot.  We bought all the wood stock we needed to build our full-scale track.

Week 2 Progress

This week I focused on finishing the wooden track model on SolidWorks. We ran into some complications on the split portion. The problem was how to support split weight on the track. We decided to use lift cables to carry the weight and hold it in place in the same plane as the rest of the track. The idea was to attached the cable on to the dead end support and vertically mounted to weight on the ground. We decided to use steel U bolts to mount the cable to the split portion of the track. I also made a SolidWorks model to show how to attach the guide rail on to the columns. The idea was simply a bolted joint. Then, I moved on to designing the Steel Full Scale structure. I used the same beams parts from the wooden SolidWorks model and converted into steel, and designed Gusset plates to strongly mount the joint of the beams and brace support. I used simple beams to make track structure because it makes easier to do the FEA analysis on the structure. I performed an Static ...

Week #5 Update - Last Week

I spent a lot time help the team to assemble the full scale track. It was pretty tiring but fun to work with wood. Since Dustin was sick, the work load split between Guojun and myself. Jack was a great help to me and my team. We worked really hard to complete the track.

Orientation Day #3

The third orientation day was meant to be having our lighting talk presentations from each team. We presented details about the Skyway Full-scale track expansion which included benefits of having an automated transit system, possible drawbacks of this system and how to solve them, and pros and cons of track designs of past teams. I was excited about presentation because the audience was actively participating. After concluding our presentations, we helped Prof. Burford to assemble the full-scale track from the Spring 2018 team. The task was completed in less than an hour because we got help from Eric and the full-scale bogie team. Once the track was built, we called it a day.
