week 11 report.

In this week, there are few things on CAD design that I have trouble on designing. These need to be solved on todya's meeting.
I have able to run FEA test on two important part.
this one is the connection between the bogie and the suspension or cart. Overall the deformation is relative low. and the safety factor is above 1.

this is the stop, which help to fix the switch wheel only rotate in a certain region. and the safety factor is greater than 1

Therefore, finding the supplier and get the correct plywood is essential to this semester.
