摘要
The present invention (A) by hitting the origin (0°) on the circumference of the rotating shell structure, the phase (φ) of the L mode times of the nth order vibration mode from the pulse wave and auto-spectrum measurement results measured at the origin obtaining two phase values for determining nL ); And (B) the phase of the L mode times of the nth order vibration mode from the magnetic spectrum result measured at the second point by hitting a second point corresponding to one of the two phase values in the rotating shell structure (φ nL ). and the crystals, φ nL and obtaining a mode pair to determine φ nH from the relationship between the n phases of the H-mode times the primary vibration mode (φ nH); vibration only vibration signals of the two points on the circumference by yirueojim including Since it is possible to determine the mode pair, the present invention relates to a method for extracting a mode pair of a rotating shell structure that can extract a mode pair very easily and quickly than a conventional method in which signals were measured at 24 to 36 points on the circumference.
