An Experimental Evaluation of the Experimental Spatial Dynamics Modeling (ESDM) Technique
… structure locations. An important new technique, Experimental Spatial Dynamics Modeling (ESDM), utilizes such spatially dense velocity data. ESDM models continuous, three-dimensional velocity fields using LDV velocity data. Thus, ESDM is a powerful structural dynamics analysis tool that …

Development of the Velocity Transformation Function of Damped Flat Shell Finite Element for the Experimental Spatial Dynamics Modeling
Experimental Spatial Dynamics Modeling (ESDM) is the new process of constructing a three dimensional, complex-valued dynamic model of a harmonically vibrating structure using numerical models and laser-based experimental data obtained from a Scanning Laser Doppler Vibrometer (SLDV). In ESDM …

Modeling and visualization of laser-based three-dimensional experimental spatial dynamic response
Experimental spatial dynamics modeling is a new approach to dynamics modeling using high-spatial-density experimental data from a scanning laser Doppler vibrometer (LDV). This instrument measures the surface velocity of vibrated structures. Time-signal data from the LDV is statistically modeled …

Sensitivity analysis with respect to elastic boundary conditions and laser spatial variables within experimental spatial dynamic modeling
Experimental spatial dynamics modeling is a new method used to obtain a dynamic model of a harmonically excited vibrating structure. The continuous three-dimensional, complexed-valued velocity field of the structure is solved from a weighted least-squares finite element formulation, making use of …
