Qualification testing demonstrates that when a structure is exposed to the type of service environment in which it is expected to operate, the overall system will meet all of its performance criteria. For aerospace products, the types of qualification tests needed typically include vibration and acoustic environments to evaluate the dynamic structural integrity of the system. Testing is often performed on electrodynamic shaker tables, in acoustic reverberant chambers, or using Direct Field Acoustic Testing (DFAT). Wind tunnel and aeroacoustic testing may also be performed.
Instrumentation is required during qualification testing to verify that the expected environment levels were actually applied to the structure, along with sensors to observe responses at critical locations to verify that the responses are as expected and confirm analysis predictions. Most qualification testing is much more than a simple pass-fail test.
ATA has considerable experience assisting with qualification test programs by providing the instrumentation and dynamic data collection systems needed to measure and analyze the results. Our analysis expertise is also instrumental in assessing results to provide a complete understanding of the qualification process.
