Team Vision for System-Level Design Phase
Our team goal for the systems design process is to incorporate materials from phase 1 and apply them to create a specific, “big picture”, concept design of our test rig. The test rig should be easily operative and include a modeled P-Pod that is able to secure up to three CubeSats during vibration. It should also be capable of causing vibrations with frequencies ranging from 5-100 Hz.
During phase 2, our team compared the vibration environments and frequencies from the top three most common launch vehicles: Delta II, Falcon 9, and Atlas V, to identify the specifications needed to successfully design and operate our test rig. Using our functional decomposition, we combined the most important customer and engineering requirements from our project definition to decide which functions are necessary in brainstorming possible design solutions. We were able to use the same functions to create our morphological chart in order to narrow down our ideas to specific system design concepts. Our ideal system concept includes operating our test rig with a piston driven system and Arduino controller. The damping system will be comprised of shocks, actuators, or springs. Plans are in place to ensure the safety the system and those operating the rig in the case of an emergency.
