Customer Handoff & Final Project Documentation
Table of Contents
Team Vision for Final Demo and HandoffIn the final phase of our project our team worked to ensure a complete product and to provide necessary documentation for future teams and users to improve upon the test rig. The walls of the Ppod were slotted so the Ppod could be assembled to the correct dimensions and fit a CubeSat with an acceptable amount of clearance between the rails. Material from previous iterations of the Ppod was used to create a 1.5U sized Ppod for earlier testing with a shorter set up time. The team acquired a MyDAQ which was used to connect the solenoid driver to the Labview code and provide a frequency signal and the necessary DC offset to avoid topping out the piston.
Engineering Requirements Assesment
Our engineering requirements are shown above color coded with green rows marking requirements our project fulfilled and yellow rows representing near misses. The most critical engineering requirement which has not been fulfilled is the goal of matching the accelerations of the vibration test profile. While we believe our testing to be close to the required values, our inability to validate during testing meant we were not able to ensure as accurate of a test as we had intended.
System UpdatesSince last phase there have been some key changes to our system design, as well as the progress of it's completion.
- We have completed all machining successfully
- We have created a table to replicate the volume typically taken up by the deployment spring.
- To combat tolerance issues and provide more adjustability, one column in each P Pod side has had its holes turned into slots. allowing for it to slide back in forth. This means we can adjust the rails around the dimensions of a cubesat within the P Pod
- Each side has been numbered and assigned a corresponding side of the base plate. This allows the user to assemble it the same way each time, limiting any unforeseen issues with compatibility or hole fits.
- The top baseplate has been machined down to eliminate any unnecessary torque from outlying points.
- Two spacer cubesats have been made. These will replicate the displacement of two cubesats in the P Pod
- A smaller "mini P Pod" has been created equal to a 1.5U P Pod. This can be used to run tests on a single cube sat rather than the volume of 3. This is more beneficial as it causes less wear on the piston.

Bill of MaterialsShown below is our bill of materials. As noted, we are still aproximately $170 below budget. This number was confirmed with the senior design office. Due to many small variations in price, and shipping costs, there is a $100 offset in there for it to match our current account.
