Dynamic Measurement in the Aerospace Industry
Engineers at leading aerospace companies frequently use Data Physics Dynamic Signal Analyzers for dynamic measurement applications ranging from rotating machinery analysis of components to large channel count modal analysis, acoustic tests, and ground vibration tests (GVT).
Aerospace ground vibration tests and flutter tests often require electrodynamic shaker systems to induce excitation in the structure. Inertial shakers are sometimes used to induce lower frequency energy in airframes and other structures. Inertial shakers can be mounted and fully supported in hard-to-reach locations on the structure. Modal shakers are most often used for structural excitation. These vibration exciters are available in a large range of sizes, from very portable models with relatively high force to models that are capable of several hundred pounds of force. Many models of modal shakers feature rotary linear bearings to completely isolate the shaker dynamics from the structure.
Vibration Testing in the Aerospace Industry
Many tests are developed to meet the rigorous demands of spacecraft and aircraft manufacturers, along with standard tests for military and commercial aircraft. For instance, DO-160, “Environmental Conditions and Test Procedures for Airborne Equipment”, published by RTCA, is required as a minimum for many commercial aircraft components by the Federal Aviation Regulations. The European equivalent is EUROCAE/ED-14D. For military aerospace applications, MIL-STD 810 and NATO AECTP-400 are commonly used. See our Testing to Standards page for more information.
