Spatial Information in Autonomous Modal Parameter Estimation
Recent work with autonomous modal parameter estimation has shown great promise in the quality of the modal parameter estimation results when compared to results from experienced user interaction using traditional methods. This includes routine data from typical automotive structures and/or ground vibration tests of aircraft or more difficult data from civil engineering structures and flight flu...
متن کاملAutonomous Modal Parameter Estimation: Methodology
Traditionally, the estimation of modal parameters from a set of measured data has required significant experience. However, as the technology has matured, increasingly, analysis is being performed by less experienced engineers or technicians. To address this development, frequently software solutions are focusing upon either wizard-based or autonomous/semiautonomous approaches. A number of auto...
متن کاملAutonomous Modal Parameter Estimation: Statisical Considerations
Autonomous modal parameter estimations may involve sorting a large number of possible solutions to develop one consistent estimate of the modal parameters (frequency, damping, mode shape, and modal scaling). Once the final, consistent estimate of modal parameters is established, this estimate can be compared to related solutions from the larger set of solutions to develop statistical attributes...
متن کاملIntegrating Multiple Algorithms In Autonomous Modal Parameter Estimation
Recent work with autonomous modal parameter estimation has shown great promise in the quality of the modal parameter estimation results when compared to results from experienced user interaction using traditional methods. Current research with the Common Statistical Subspace Autonomous Mode Identification (CSSAMI) procedure involves the integration of multiple modal parameter estimation algorit...
متن کاملClustering Approaches to Automatic Modal Parameter Estimation
Most modal parameter estimation techniques utilize Stabilization/Consistency Diagram as a tool for distinguishing between physical system modes and mathematical modes. However, this process results in giving several estimates of the same mode and the task of choosing one estimate over others is left to the user. This task is highly judgmental, with user expertise playing a big role as to which ...
