Update
From last Wednesday meeting, we looked at our concept designs and discussed the advantages and disadvantages of our sketches. one of the things we agree on was creating a small track on the top of bogie system and use the hydraulic actuator to raise extra arms to use as steering guide-way. However, some of us learned from Dr. Furman that we will be modifying the existing bogie system and railway. We were constraints on the exploring the new designs since the existing steering mechanism is fully developed and there is very little changes we can improve on. After that, we discussed with fail/safe team and get some of their ideas on what their thought about the bogie system. I learned from one team member that he wanted to use the bogie system similar to roller coaster as a fail/safe. We brainstormed even further into what changes that can improve the system significantly and we agreed on reducing vibration and noise during the operation.
Idea:
I have been doing research and read more into old project reports from previous years for steering mechanism design. I tried to figure out the significant changes that can improve the steering mechanism even further without altering the structure of the system. One of the important things that last year reported was d
esigning of a system can keep
the steering wheels firmly pressed against the surface of the track. Since the wheels on steering mechanism are adjustable but they do not provide any type of active adjustment to hold them securely on the track. After doing some search, the only option that I can think of is using stronger actuator on the steering mechanism to create more force applying on the steering wheels, making sure that the wheels do not disengage from the surface of the track. Furthermore, I thought of magnet strips that can be installed inside the steering wheels and on the inside surface of the track to act as an passive system for keeping the wheels align and securely engaging on the course.
