Week 7 Update

10/4/2018


  • Team consulted the track team for dimensions
  • cleared up objectives we need to finish before semester ends
  • Had a FEA learning session as a team
  • Began FEA procedure on guide arm assembly.
  • Went over ideas for Rapid prototyping for emergency braking system

    Full Scale Drive Train Team:

    Please post your dimensions and other specifications here. What were the objectives you needed to finish before Fall 2018 semester is over?

    What are your initial FEA results, and what do they mean?

    What were your ideas for rapid prototyping an E-brake system?

    Please be more detailed with your blog posts. This is not enough.

    What is your progress from last week? Where are you at in your designs?

    Designing articulating axles of the bogie.
    Designing spring loaded guide arm
    Designing emergency braking system.
    Providing mounting points for the hub motor axles to motor team.

Week 12

Week 11/17/2018                                                                        Full-Scale Articulation and Brakes Articulation          We were able to get solid work models of early versions of the new slave bogie. we are currently working on trying to incorporate the new articulation system to the updated slave bogie. We will need to make some adjustments to some side panels of the wheel housing so that it does not interfere with the articulation system. We will need an FEA after the parts are cut to see if the structure still retains its strength. Pins are still being modeled. we might just use premade pins (if available) to reduce manufacturing cost. Guide Arm (Akash Sandhu)        For the guide arm, I was facing two problems. As discussed ...

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 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 ho...
