<p><P>PROBLEM TO BE SOLVED: To provide a vibration analysis method of a piping system and a vibration analysis device of a piping system for easily performing vibration analysis even to a piping system with a complicated shape. <P>SOLUTION: Disclosed is a vibration analysis method of a piping system for performing the vibration analysis of a piping system 1 by: a division process (step S6) of dividing the piping system 1 into a plurality of elements 6<SB POS="POST">k</SB>for each restraint point 8; a reference model allocation process (step S8) of allocating a reference model 7<SB POS="POST">k</SB>whose characteristic frequency X<SB POS="POST">k0</SB>is known about each of the plurality of elements 6<SB POS="POST">k</SB>; a correction coefficient calculation process (step S10) of calculating a correction coefficientα<SB POS="POST">k</SB>based on a difference between each element 6<SB POS="POST">k</SB>and the reference model 7<SB POS="POST">k</SB>allocated to the element for each of the plurality of elements 6<SB POS="POST">k</SB>; and a characteristic frequency calculation process (step S12) of calculating characteristic frequency X<SB POS="POST">k</SB>of each of the plurality of elements 6<SB POS="POST">k</SB>by multiplying the characteristic frequency X<SB POS="POST">k</SB>of the reference model 7<SB POS="POST">k</SB>allocated to each element 6<SB POS="POST">k</SB>by the correction coefficientα<SB POS="POST">k</SB>. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
