Small Scale Bogie Design Team_LS

SEPT. 26th 2018--Small Scale Bogie System Task Items: -Develop a thorough schedule including dates of assignments.  -Continue research. -Think of concepts. -Look more into specific design criteria. Summary: Today all teams presented their presentation regarding an overview of their project including their purpose, goals, functional specifications, and plans. In regards to the Small-scale bogie team's presentation, the necessity in preparing for future presentations is clear. Evaluation of presentation criteria will should be done earlier to allow adequate time to develop meaningful and organized content.  At the end of the Small-Scale Control team Professor Furman commented on the use of gimbal motors as an alternative to brush-less motors that provide high rpm. At the end of my presentation Furman relayed that the bogie design is a candidate for injection molding were the design geometry of the bogie will need to be reviewed in the future.

SEPT. 19th 2018--Small Scale Bogie System (Day 4) Task Items: -Include friction calculation to proposal. -Prepare for Presentation for next class.  Summary: The beginning of class was used for presenting team's revised proposals. Small scale went first and determined where one group's responsibility ended and others began. Professor Furman commented on including friction calculations to handle the gradeability proposed by the track team. The need for multiple bogie design to meet the expanding track is becoming more necessary. This will increase the work but will allow for multiple design concepts.  Progress: Revised proposal. Multiple chassis design concepts include: H-frame, C-channel with cross-members like a vehicles. 

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 volum

SEPT. 5th 2018--Small Scale Bogie System (Day 2) Task Items: -Continue Brainstorming -Project proposal (Due Sept. 8th 11:59 pm) -Develop Specifications -Continue research -Begin developing budget -Think about schedule Summary: Today the class went through their lightening talks describing their focus on the project. The small-scale bogie presentation is linked at the bottom of this post. The following groups presented: Full-scale Bogie/Guideway Interface* Full-scale Controls  Full-scale Drivetrain* Full-scale Solar Full-scale Wayside power Half-scale bogie* High Power-density Motor Small-scale Bogie Small-scale Controls* Small-scale Track* *Groups to establish communication with for ideas, assistance, and concepts. After the presentation I met with the small-scale track and small-scale controls teams and discussed different concepts and analyzed last years design.  Progress: Focus will be mainly on improving drive system as it was the main issue with

AUG. 29th 2018--Small Scale Bogie System (Day 1) Task Items: -Create Team Blog -Brainstorm Ideas for brief presentation next class -Research Current issues for the existing bogie design include: 1.) Motors burn out after exhibit. 2.) Wear and Tear on the wheels due to equal power distributed to each wheel during turns. 3.) Binding at the joint that connects the master and slave system. Suggestions: -Differential -Flanged or Conical Wheels -Better motor
