The Design of Modal Analysis System Based on an Improved Algorithm of Discrete Orthogonal Polynomial

Abstract:

An improved algorithm of the discrete orthogonal polynomial to identify the modal parameters is stated and a modal analysis system is designed and developed by object-oriented programming language Visual C++ here. Then proper experiment device is setup to collect signal data. Finally, compare the algorithm’s result with the ME’scopeVES’s and exam the algorithm’s correctness.
