The SMAC Modal Parameter Extraction Package
Conference
·
OSTI ID:1063
After the basic theory for SMAC is presented below, two applications of the algorithm with real hardware will be presented. The first moderate-damping application is a system with approximately 50 modes in the bandwidth with up to 5 percent damping. The second application has at least 70 modes in the bandwidth, but damping is always below 3 percent. In addition to the improved implementation of the SMAC root finder, coding has been written to extract the mode shapes based on quadrature fit, and this is described herein.
