Project:
Motion Based Flight Simulator Vibration Testing
Customer:
FlightSafety 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:
- Define test objective
- Provide description of flight simulator and the areas of interest
- Describe 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
- Develop accelerometer/signal map and test configurations
- Develop accelerometer location map based on peak deflections from system finite element model
- Summarize tests performed
- Composite Structure analysis
Instrumentation Mounting and Testing:
- Set up data acquisition system at customer site
- Document accelerometer signal map and mounting locations on flight simulator
- Perform vibration tests and monitor data during acquisition
- Post process a limited portion of data immediately following test to ensure quality
Vibration Data Processing:
- Plot all data using NI Signal Express software with accelerations, approximately 200 plots
- Process the reference response at the motion system knuckles to characterize the drive signal
- Develop calculation for relative deflection between display mirror and the inner support frames
Conclusions and Recommendations:
- After processing and reviewing the data, PEI developed a series of observations
- Recommendations were provided to the customer for design modifications
- Generated test report
