Vibration Measurements In Aerospace Development

Structural testing is an integrated part of aerospace product design, development and manufacture. It is an essential step to ensure performance, quality, safety and reliability in the final product.

Today's market pressure for new, affordable high performance aerospace products is increasing the number of product variants and the complexity of tested structures. Product development and design refinement teams are requesting more efficient modal testing to increase throughput, while maintaining accuracy adequate to correlate with FE analysis models (i.e. load analysis, acoustic radiation, etc.).

In addition, these new structures require a substantial number of spatial data points. The combination of more structures and and more measurement points is rapidly increasing the costs of doing a traditional modal test with it's labor intensive approach of instrumenting structures with accelerometers and multi-channel data acquisition systems.
