Week 11 Update
For this week, we decided to continue on with our design of the junction as well as providing the full column assembly so that FEA could be performed. We want to be able to finalize our designs as soon as possible to focus on working with the analysis to provide to other teams (such as the Solar team). We are still on track to presenting soon, and are hoping to have many of our designs finalized with little to no changes made. Below is our new track assembly and the new dimensions.
For this week, Evelia focused her attention on updating the third rail and redoing the analysis to check if there were any changes. The reason for the update was due to the Interface Bogie Team's newest design. Their switching wheels on the bogie are standing at about 20.7" (525 mm) above the track. Our original supports were 10" and now they are about 3.88" (90.52-mm). The FEA for the new design can be seen below. We will continue working on the third rail and junction as well as getting the FEA done for the column soon.
New FOS is 15
Maximum displacement is 0.066" (1.685-mm)

I am happy to see so much CAD work and analysis (FEA) completed by your team! So good job to you both.
ReplyDeleteWhat are the overall dimensions of your track going to be? How far will the curved section of your track be? Will your track design mimic the layout of the old metal full scale track that is in the back of the shop?
