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