“…Machine learning can also be used for model order reduction [190,191]; manifold learning and manifold processes for model order reduction should be discussed in detail in our future work. Chaos features can improve the efficiency of reduction models [192][193][194] and the combination method of uncertainty quantification [195,196], and model order reduction will be efficient to study the complex dynamic systems. Another point is the systems with substructures.…”

“…The stiffness value of the hoop is dispersive, and the stiffness value obtained by static test may be quite different from that of the hoop in real pipeline system [34]. In this study, the corresponding stiffness and damping values can be obtained by inverse identification method [35][36].…”

“…The natural frequency under the tightening torque of 10Nm decreases by 2.1Hz with the increase of the excitation amplitude. This may be caused by the uncertainty of clamp-pipeline system responses [9].…”

“…The results show that the natural frequencies and mode shapes of the reduced model are the same as full FE, but the calculation is faster. Guo et al [9] proposed a nonintrusive multi-dimensional Chebyshev polynomial approximation method (M-CPAM), which is used to study the frequency response of a clamp-pipeline system. The results show that under the same pre-tightening force, the stiffness of a clamp has greater dispersion, and with the increase of tightening torque, the dispersion of the clamppipeline system tends to be concentrated.…”
