Week 3: Finalizing Function Specifications

SEPT. 12th 2018--Small Scale Bogie System (Day 3)

Task Items:
-Finalize feature specs.

Summary:

Everyone went to their respective groups and worked on finalizing their feature specs. We had Kevin, who was on last years small-scale track team, visit the small scale squad and where he gave us some insight. As far as information related to the bogie he insured that the motors would need to be changed, for they burned out, and for determining bend radius he recommended looking into how trains do it. 

 While with the small scale squad was together we established a line of communication through a shared google folder and also a group chat using Slack. We discussed the possibility of producing three functional bogies to have running on the track. Whether it will be three different designs or one design reproduced will need to be decided. 

Progress:
The following items will need to be quantified in order to complete the functional specifications:
Weight
Speed
Size (Build volume)
Grade
Acceleration
Run Time
Power Consumption and Rate

Week 10: Prototyping

Oct. 31 Small-Scale Bogie Team The controls team and I talked about the selected  gimbal motor. Some concerns were raised about it not having a shaft and upon further investigation it was found that half of the motor enclosure would rotate not just the shaft. This will make mounting the motor difficult and we should look for alternatives. The need for a functioning test track and Bogie set up are hitting high demand and will most likely be the small scales topic for discussion among other things. As far as inductive charging the integration will be lead by the controls team with little Bogie involvement as it does not dorectly effect Bogie design.

Week 11: Small Scale Bogie

NOV 7th - Small Scale Bogie Improvements Team Within this week I tested the use of flanged conical wheels to assess the feasibility of using them for passive turning on the track. The initial design was referenced to an existing design that had a slight angle to the wheel of about 3 degrees. Two wheels were attached to an axle and by gravity was allowed to roll down a curved track. The wheels unfortunately did not move as desired and rather continued in a straight line. A new set of wheels will be tested with a greater angle. The updated design is shown below which has a 25 degree angle. Updated Conical Wheels

Week 7: Rapid Prototyping

OCT. 10th 2018--Small Scale Bogie System Task Items: -Continue developing concepts -Obtain dimensions of components  Summary: This weeks class consisted of a quick meeting which eventually lead to everyone dispersing to their respective groups. While in groups I talked with the small-scale track team to overcome an issue with the track at the three-way junction. At the junction there was a large gap the bogie would surely fall through so it was decided to stagger the turns so one is behind the other.  Additionally, I spent time reading an article consisting of all the major modules for a bogie along with the different configurations. The article can be found below. The article helped map out possible concepts that I can build up on and replicate a more feasible design. To create functional parts, I will need to find the dimensions of all the components going on the bogie and create CAD model. After the models are created then I can build up the bogie.
