To quantitatively identify the transfer paths and evaluate path contributions of shell structures, an singular value decomposition- (SVD-) and principal component analysis- (PCA-) based operational transfer path analysis method is constructed and studied in this paper.
Firstly, SVD is used to determine the contribution of each path and reduce crosstalk.
Secondly, PCA is applied to reduce the influence of unwanted frequency components and thus reduce noises.
This allows the presented OTPA to be more accurate than its traditional counterpart.
Once the transmissibility function is obtained, the response synthesis is determined, and the transfer path analysis and path contribution evaluation can be effectively carried out.
Numerical and experimental case studies are carried out to validate and test the performance of the presented method.
Furthermore, a comprehensive observing the influences of correlation between sources and distance of sources and receiver is also provided.
Generally, this paper provides accurate transfer path analysis and path contributions for mechanical systems, which can benefit vibration and noise monitoring and reduction through vibration reduction structure design for new equipment or vibration damping on the major vibration transfer paths for current equipment.
