Week of 6/05 Bogie Team Update

Bogie Team Daily/Weekly Blog

We started off by drilling holes into pieces of metal and into the top frame of the bogies, so 2 wheels could be mounted at the the top of the frame on both front ends of each half bogie. We sanded down the holes we drilled, so there wasn’t any sharp metal pieces sticking out. Wheels were assembled onto these steel pieces with a threaded shaft and fastened by metal nuts with washers in between. The threaded shafts had to be cut using a metal cutting chop saw.to be implemented into the bogie. We began changing the Solid works model to address these changes

The new steel pieces were assembled onto the bogie. After we did that, we put the bogie back on the track and tested if it would run correctly on the track. At first it ran smoothly, but when we tried to push the other way, it was getting stuck against the wood ceiling, just like before. But we could realize that the new steel pieces that were assembled to the bogie, make it ran way easier than it was without it. Also we had a lot of new ideas for the retractable model of the bogie, we’re planning to start working on that tomorrow.

Two wheels were attached to the back ends of each bogie (where the motors were attached initially) to see if this would correct the issue the bogie was having on the other side of the track.We tried to grind down some extruding welds on the track and on the bogie, but this didn’t solve the problem.  We realized that there may be some imperfections in the track that may be causing some of the issues were having. We began working on a new design in Solid works for the bogie to implement the changes we have done to the previous bogie. The sub teams of propulsion and braking began to research their topics.

We started off the day by organizing the metal in the shop. Afterwards, the mechanical portion of the team continued to work on the new design for the bogie to address the changes that were physically done on the bogie. The propulsion sub team continued to do research and began to brainstorm and sketch different ways to implement an actuator that would push the motor's’ frame to add a greater normal force to the motor and the wooden ceiling.
