Week 1-SSDC

The focus for me this week was to work on of the scope of works for the Full-Scale Bogie. The scope of work that I worked on particularly is a designing a belt tensioning system for the drivetrain of the bogie. The previous team before us had implemented a belt driven system to transfer power from the Permanent Magnet DC motor to one of the axles on the bogie. However, the goal of the current Full-Scale Bogie Team is to add to the current design a a belt tensioning system. I then explored methods to tension the belt automatically to help cope with wear and any thermal expansion the belt might experience. After research online and drawing multiple iterations of possible design, I arrived at a possible solution that would had a third pulley to the current system. This pulley would then be attached to spring where the pulley is allowed to slide on a slot cut into the bracket. The designed was first sketched by hand, and then reworked in SolidWorks. Below are two of the CAD images. Dan later suggested that I try attaching the tension system directly to where the motor is currently mounted to help save time and make the design more simple. Topics that still need to be considered are the type of belt that should be used. Furthermore, there is still needs to be exploration in to finding  parts that remove the need for anytime of slot as Dan suggested.

Week 3 Update

             First, I prepared for the presentation. Then, I shifted my focus on completing the Bill of Materials. Afterwards, the team and I combined orders with the other teams to purchase items from McMaster-Carr.  I also went to sims with the team to obtain material that was not available at the shop. Then, I was the lead for sending the order to Kyle for getting parts water jet cut, so first the team spend time creating DXF files. However, the water jet at school is under maintenance. The goal was to combine orders with wayside and suspension, but after the set back there were changes in the plan. I ended up calling many local fabricating and machining shops. The problem was that the laser cutting could not cut the thick steel or cut wholes that were smaller in diameter compared to the thickness. Furthermore, many shops had a lead time of 2-4 week before they could start working on our parts. I was able to find one laser cutting shop and two water jet companies. Metal Werx, one of

Week 4 - Update

Week 4 Update             Firstly, I dropped of the material to get both Wayside and Bogie team parts water jet cut.  I worked with the team on lathing the aluminum rod that would go through the thrust and flange bearing. The belt and new pulley were also test fitted. I also went with Eric to pick up parts from the water jet company. All other parts except one parts were cut correctly. I helped the team with attempting to mill the aluminum plate. Dr. Furman suggest that we go the Central Shop to fix the plate. I worked on sanding metal parts also and chamfering them, so the team can get the parts welded on. I was also able to fit in the two flange bearing with the help of Alan. Some welding was done on Thursday, however, there is needs to be a few more parts that need welding.

Week 2 -SSDC For this week, I worked with the team on some parts of the articulation of the bogie and did research on how to use a thrust bearing as Dan had suggested. Furthermore, I changed the design of the tensioning system to make it more simple and use the current motor mount as Dan suggest. I then created a bracket that pivots around one point on the motor mount as it tensions the system with spring.  I also worked on finding parts and updating the Bill of Materials. Firstly, the systems team did not know what pulley they were going to attach to the shaft of the electric motor. I then found a pulley for the shaft which has teeth as a recommend feature by Eric. I also found the approiprate spring on McMaster-Carr. Pivoting Tensioning System
