Week 8

Week 8 update
Steering Rack

  • mounting points for steering rack were determined.
  • the team will be using Unit strut to bolt down the steering rack.
  • The mounting point are shown in the following image.


  • The dX (6.74in) is subject to change when final FEA analysis is done. this would effect the current way that the unit strut is set up.
  • Current  height of steering rack will be 6.4 inches from bottom surface to top


Guide Arm
  • team is working on solidwork models of the guide arm
  • FEA analysis was done on the guide component.
  • Dr. Furman recommends a incorporation of damper into the system to make motion more smooth
  • Calculation of the force acting on the wheel was performed using Matlab
  • The full design of the guide arm is available on individual post from two weeks ago.


Braking system 
  • Breaking system was relocated from the inside of the track to the bottom 
  • This new design will allow the brake pads to press on the bottom of the tracks to slow the bogie down in case of an emergency. 
  • The new location allows us to use bigger and stronger springs, and it solves the problem where the brakes are never at a constant distance from the track.

    Full Scale Drive Team: I am happy to see some CAD and FEA results completed.

    It will be great once you have all of your sub-systems designed in Solidworks and integrated together on the chassis of the bogie. Perhaps 3D print the guide arm as a rapid prototype to ensure it will work as intended.

    Be sure to keep open communication with all of your sub-teams, as you very well know it is difficult to integrate many sub-systems in the end.

Week 10

Week 10 this week the team worked on finishing up solid work models and conducted FEA on most of them Through rapid prototyping we were ale to see that our designs had a few problems that needed to get fixed before the final product. Articulation The problem with articulation structure where it would fail when loaded with 2500lb was fixed by adding a small section that helped reduced the moment arm caused by the bearing carriage. Shown in next figure.  The following figure shows the redesigned part. This new design greatly reduces the moment arm allowing the structure to carry more weight. This design has a factor of safety of 8.86 this means there is alot we can do to improve the design and reduce its weight from current 14 pounds. Since the bogie will not be using an axle we had to think of a new way to mount wheel housing to the new articulation system for now we designed this component which works as a carriage for the thrust bearing and also has mounting holes

Week 11, For this week the team continued to work on our individual components Articulation: currently redesigning thrust bearing carriage, need to consider there being an axle that connects both wheels together. currently designing pins that will lock in place for the steering rack, Guide Arm: currently working on improving on the design for the spring holder and wheel holder the Safety factor is really high attempting to decrease material and make design changes to improve design and optimize for safety of factor above 2, but not extremely high. images of the components are provided that show area where material can be removed. furthermore, the prototype should a concern a different loading concern when it comes off of switching tracks, the force will not all be perpendicular to the track, so additionally FEA was done with different loading conditions. minimum Factor of safety = 27 goal for next week start report Redesign the "arm" for the

Week 13

There is less than one month before this semester ends and we are starting to shift our focus on to our project report. We feel that we have enough information to discuss our progress. We have made significant progress with our designs and will continue to tweak and improve details. We have ran FEA calculations and have made prototypes to test out our designs. With finals coming in a few weeks, we would like to make significant progress to our report each week and hopefully have our reports completed before the week of December 10th. Guide Arm I have added mounting points to the guide arm for the drive bogie, and have tested that it fits the drive bogie. Now the interaction team needs to add mounting points to the drive bogie. Last, there was also focus on completing the last individual writing assignment. The goal is to determine mounting points for the slave bogie next. FEA was also completed on the guide arm with these new mounting points, and two different loading scenarios wer
