-In the first design, the AEV used two motors, metal braces to secure the motors, a flat base, and metal braces to hold the battery. This design was extremely heavy and used the most energy of any design tested. -For the second design, the AEV used a single motor with no additional braces required to hold the motor, a flat base, and metal braces to secure the battery. This design was significantly less weight than the previous design, which allowed it to coast along the track for greater distances and use less energy during its run. -In the final design, the AEV used a single motor without additional metal braces, a vertical base, and a small piece of plastic to secure the battery. In this design, a 90-degree metal brace was also added to the front of the AEV in order to pick up the caboose. Changing the AEV’s base from vertical to horizontal and substituting the way in which the battery was held made the AEV have less mass. The group’s final design used the least amount of weight possible because the group had proven that this would lead to the AEV using the least amount of energy per run. Advanced Energy Vehicle Design Project Patryk Moeller, Steven Moliterno, Nicolas Pouliquen, Cody Willman Group Goals Each group member generated a design that could be potentially used as the AEV - Two of the Orthographic drawing were combined to create an the groups initial AEV build -In the process of creating the design of the AEV, the group had to decide between different design options - One Motor or Two Motors - Wings or Wingless - Durability or Efficiency - Push or Pull Motors -To make these decisions and compare designs the group devised a scoring chart Benefits of Final Design and Coding: - Simplistic/lightweight design - High durability - More energy efficient runs - Greater coasting distance The group came to the consensus that the AEV’s final design and code met all of the group’s original goals Goals of the project: -Build an AEV that will run on the track -Use the AEV to travel on the monorail to pick-up a caboose at the end and then return safely to the starting point -Construct an AEV that would use the least amount of material to minimize the AEV’s weight -Program the AEV to use the least amount of energy during the run Ultimate Goal: -Successfully construct an AEV that will meet all of the requirements while using the least possible amount of energy Design Process The Single Motor AEV Design Progression Final Design Programming AEV MethodEnergy Used (J) Run 1 - Constant Motor Speed Run 2 - Burst and Coast17.18 Group K Professor Schrock GTA John Zakelj -The group wanted to program the AEV so that it would use the least amount of energy during the run -There were numerous commands that could be used to run the AEV, so the group measured the energy used for each command l -With the knowledge gained from the above graph, the group generated two methods of running the AEV and determined which would use the least amount of energy -Constant Slow Motor Speeds -High Powered Burst then Coast -It became clear to the group that the Burst and Coast Method would use less energy The Final Design of the AEV would be the single motored AEV pictured above. This AEV stood alone as the only single motored AEV in its class. This design cut out all unnecessary weight and used the fewest, lightest parts possible. Minimizing the AEV’s weight would lead to less joules of energy being used during each run.
