Parameter Selection Strategies in Finite Element Model Updating
(The American Society of Mechanical Engineers (ASME), 1997)In FE model updating, as in any identification procedure, we select some parameters in the model, and try to fine-tune them to minimize the discrepancy between the model predictions and the ... -
A Two-Step Structural Damage Detection Approach With Limited Instrumentation
(The American Society of Mechanical Engineers (ASME), 1997)This paper describes a two-step damage detection and health monitoring approach that was developed for large and complex structures with a limited number of measurements. The first step identifies ... -
Frequency Domain Modal Parameter Identification of High Order Systems in a Numerically Stable Way
(The American Society of Mechanical Engineers (ASME), 1997)Frequency domain modal parameter identification methods have several attractive properties as compared with the time domain methods except for the limitation of low-order-and-narrow-band per analysis. ... -
Mechanical and Electrical Run-Out Removal on a Precision Rotor-Vibration Research Spindle
(The American Society of Mechanical Engineers (ASME), 1997)Experimental determination of both steady-state and dynamic performance of a journal bearing requires the use of a high precision spindle with a vanishingly small range of run-out. This was ... -
