Project Overview:
Conduct motion-based flight simulator vibration testing
Customer:
Flight Safety Visual Systems
Services Performed:
PEI developed a test plan, mounted instrumentation, ran tests and recorded data, processed the data, and provided conclusions and recommendations.
Test Plan Development:
- Defined test objective
- Provided description of flight simulator and the areas of interest
- Developed the test setup and hardware
- For vibration testing 14 triaxial accelerometers utilized
- National Instruments (NI) data acquisition system with chassis, input modules, and synchronization modules
- Dell M6700 laptop running NI Signal Express 2015 for data acquisition and processing
- Developed accelerometer/signal map and test configurations
- Generated accelerometer location map based on peak deflections from system finite element model
- Summarized tests performed
Instrumentation Mounting and Testing:
- Set up data acquisition system at customer site
- Documented accelerometer signal map and mounting locations on flight simulator
- Performed vibration tests and monitor data during acquisition
- Post-processed a limited portion of data immediately following test to ensure quality
Vibration Data Processing:
- Plotted all data using NI Signal Express software with accelerations, approximately 200 plots
- Processed the reference response at the motion system knuckles to characterize the drive signal
- Developed calculation for relative deflection between display mirror and the inner support frames
Formal Test Report:
- After processing and reviewing the data, PEI developed a series of observations
- Recommendations were provided to the customer for design modifications
- Generated test report
