Testing at Delphi

- Vibration:- Originally planned on Sine Sweep- New plan is to run 4G RMS test- 6 total tests minimum planned

- 2 in each coordinate plane

- Temperature:- Cold/Hot soaking capabilities at facility- If time permits, will look at doing a test after cold soak

- Shock Test:- Looking into doing a 27 G shock test

Simulations - Modal Analysis

Simulations - Random Vibe

Simulations - G force loading

Switch Placement Verification- Adjusting switch location for final placement- Washers/nuts do not give enough fine adjustment- Opted for threaded rod instead of shims

- 4-40 rod offers .003” linear movement per ⅛ turn (indicator on back face for ⅛ turn)

Future Plans and Needs

- Design/Manufacturing:- Drill final mounting holes once proper location is

determined- Testing:

- Pressure testing (Bell Jar) to verify switch location

- Vibration testing at Delphi- NASA Meeting:

- Meeting with an alumni from NASA. Okay to give overview of project?
