Integrated System Build & Test

Team Vision for Integrated System Build & Test PhaseWhat did your team plan to do during this phase?
- Analyze sound frequencies of the cannon recordings
- Test the window sash with audio set-up
- Work on the deliverables for this project
What did your team actually accomplish during this phase?
- Testing started with more details below in Test Results Summary section
- Window pane broken during fixture movement, not exposure to sound
- Arrange details and information for Imagine RIT booth
- Prepared draft of poster for this project
- Maintained contact with Imagine Committee, HSE members, and RIT Public Safety about noise concerns
Test Results SummaryGoal: Meet Engineering Requirements 1,2, and 5.
- ER1: Maintain sound level for spectators
- ER2: Measure current damage
- ER5: Keep sound level below damage level
EquipmentThe following items were used to test the window panes against recorded cannon fire:
- Laptop - Has audio file on it. Connects to amp with aux chord.
- Amplifier - 80W Guitar Amplifier.
- Window Sash & Mounting - made by the team.
- Linseed Oil Putty - two window panes have new putty applied, others are unchanged. Both can be see in the image below.
Expected ResultsOur team expected to learn the following from conducting these test firings:
- Ability to conclude if the low pressure frequency waves are the primary cause of movement and damage
- Estimate for window life measured in number of "cannon firings"
Proof of concept testing was completed to ensure the audio setup could output sound at appropriately high levels and that the test setup was functioning as intended. We found no faults in our system and continued to the next step.
High Speed Testing
We used Dr. Kinsman's high speed camera to capture the displacement of the window caused by the sound waves. They were not as high as initially predicted, even at max volume. Note that the sound was exceeding the volume experienced at GCV&M during our on-site test.
Future TestingThe problem seems to be the output of the amp. currently waiting on contacts to get back to us about a stronger bass amplifier to more accurately replicate the sound wave. An air cannon is also being sought out as a backup to replicate the blast for testing.(courtesy Blackbox Biometrics)
