Week of 09/26/2018 to 10/03/2018

During this week, I was able to come up with a design for the emergency braking mechanism. The emergency system consists of an  electromagnet, which is connected to a slider assembly and brake pad. Calculations were performed and determined the amount of force needed to stop the bogie within 18 meters. There is still some ambiguity in the project, as we do not know whether we are keeping the old bogie or building a new one. 

Space is also a big issue since the braking system needs to fit within 12cm of width. Several braking assemblies are going to need to be implemented on the bogie to have it stop within 18m. To design the braking system adequately, the total mass of the vehicle will need to be known. The mass and velocity will have correlation to the amount of kinetic energy of the vehicle. Below is a diagram of how the emergency braking mechanism will work.

Final Week

This week we delivered our final presentation on the Spartan Superway project. The end result was amazing and E-Brake worked better than I had expected. The alumni event was a great experience as I demonstrated my project to many people. Overall the Spartan Superway project has been a great experience and I have learned so much. I hope the coming years' team will continue to work hard to hopefully bring this project into reality. Jaspreet Singh

The emergency braking is almost ready for testing. The manufacturing is almost complete with an exception of the welding work. The parts have been sent out for welding and I will get them back on April 29th. After the parts are put together, I would like to start testing to ensure that everything is in working order.

This week I was able to get all of my parts welded from Huffman's Welding in Newark, CA. The parts came out excellent and the next step is to be to assemble everything and begin testing of the system. The picture below shows the welded parts.
