Week 14: Presentations

In class presentations were given to which none of the small scale was able to present due to time constraint.

From the Gantt Chart, this week marks the beginning of the FEA analysis for the bogie design. The main areas of concern will be the articulating joint and servo arm for track switching. Last years arm model was able to achieve a safety factor of 8.5 which should be similar to this years model as it is similar. However the linkage system will also have to go FEA to ensure that there is not failure at the joint where the parts are expected to have the least material. The articulating joint will go under similar analysis.

Week 11: Small Scale Bogie

Image
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 8: Lecture

OCT. 17th 2018--Small Scale Bogie Task Items: -Continue developing concepts -Create presentation Summary: For today we had about two hours to work on our project before meeting on campus for a lecture. Within the two hours I researched some more design concepts and looked up presentation requirements. The design concepts developed so far resemble that of a car frame allowing space between rails for placement of the drive components. Typical bogies utilize an H-frame design and will influence further design. The lecture discussed the effects of technology and social interaction. We conducted a survey and discussed in groups what we put down. A few groups presented in which most agreed that technology has had an effect on social interaction.

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. Article:...
