At this point the frame of the car has been custom built by
the team before I arrived for the project. In the following weeks we will
continue to add crucial systems for the cars. The task assigned for me during
the week was to create bushings out of a high strength plastic to use as a
placeholder on the car to attach other parts such as the a arm suspension
system. These plastic bushings are used to make sure the pieces fit and
everything works and won’t be the actual material the bushings will made of.
Eventually we will remake the bushings with a type of metal which will be used
in the actual competition. The reason we use the plastic to prototype the
design is because it is a lot easier to manipulate and shape, but has a huge
flaw: it expands greatly in the presence of water causing the pieces not to
function properly. We used lathes to fabricate these bushings and it is a slow
time consuming process because we need to get the pieces into an exact size.
This is the 5th year the polytechnic team is participating in the
competition and the team continues to grow every year. On Friday ASU
Polytechnic had an open house for extracurricular activities and we had a great
turnout for the Mini Baja SAE team. We were able to showcase previous cars to the
public and they loved what we are doing.
Were the previous cars drastically different than the one you guys are building now?
ReplyDeleteIs there a way to coat the plastic so that the effects of the water can be minimized?
