Updated TVA: A new TVA mass was machined from steel to function as a prototype for testing before the final stainless steel mass is fabricated. The mass was designed to weigh 0.765 kg, which gives a target vibration frequency of 11.4 Hz. After machining the mass was weighed to be 0.755 kg. 10 extra grams were taped on during testing to account for the difference.

TVA shipping pin:

Shipping Pin

The TVA shipping pin and plastic insert designs functions to prevent any displacement of the TVA during shipping. With the insert in place and the bolt hand-tightened, all motion of the TVA is prevented, even under vigorous shaking. The plastic insert needs to be 3D printed again to better fit the new TVA design.

Piston arrester: Tested the use of extra foam (from Pelican cases) stuffed into the open end of the piston. This method held the piston head in place, even under vigorous shaking. When loaded in the cases for shipping, the acrylic cover would keep the foam from falling out of the piston tube. While all motion of the piston head was stopped, there was some small motion of the flywheel (~1/4" displacement) under vigorous shaking. This was deemed to be acceptable by the team.

1. Accelerometer data was not centered in graph Solution: was to normalize the data rather than simply subtracting the offset.

2. Motor control is not working. Solution: we have not resolved this problem yet.

3. GUI is not updating the graph Solution: we have not resolved this yet.

4. The cables are not robust enough to withstand bending Solution: We have thought of several ideas and will likely need to remake cables with non-solid core wire. We have ideas for wrapping the existing wires in heat shrink, then automotive wrap and then a mesh sleeve.
