Abstract

A new method of computing optimized multi-point excitation force vectors for phase resonance testing is introduced. Based entirely on experimental data, the locations and force components that yield the best approximation to the phase resonance criterion are determined and the corresponding mode indicator function is predicted. The proposed method uses a minimization criterion for the measured real-part response of the test structure and does not require further information such as a mass matrix from finite- element models or assumptions on the structure's damping behavior.
