Investigation about unexpected effects of Chebyshev and Hilbert approach on using CSLDV

연속 스캐닝 진동계를 위한 체비세프와 힐버트 방식의 비교

There are some methods fur extracting mode shapes from a continuously scanned data such as a modulation, Chebyshev polynomial, and Hilbert approach. In this paper, Chebyshev and Hilbert approaches were investigated through the numerical experiment first. As some experimental parameters were altered with small quantities, data were checked and plotted. From those results, the effects of unexpected parameters will be configured. And then, it will be actually helpful to select the proper method for specific testing environments.
