Frequency and Spatial Shaping of Inputs for Multiaxis Shaker Testing
Controlled amplitude and phase relationships between multiaxial shaker inputs (i.e., spatial shaping) provides for more realistic simulation of a service environment than does conventional frequency shaping alone. Spatial shaping is described in terms of a basic mathematical model relating test arti...

| description | Controlled amplitude and phase relationships between multiaxial shaker inputs (i.e., spatial shaping) provides for more realistic simulation of a service environment than does conventional frequency shaping alone. Spatial shaping is described in terms of a basic mathematical model relating test article response (absolute and relative motions) to excitation by the shaker. Advantages and objectives are viewed through spectral relationships. The objective of simulating dynamic responses as in service is shown to be the duplication of the resultant cross-modal response for all important modes, even if the sources of excitation in service are unknown. |
