Title:
PRESSING FORCE EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/208492
Kind Code:
A1
Abstract:
Provided is a pressing force evaluation method for evaluating a pressing force upon a support member of a tube group positioned in a fluid and supported by the supporting member, said method comprising: a pressing force setting step of setting the pressing force of the tube group; a probability density function computation step of computing a probability density function of a reaction force received by the support member from the tube group for a specified input, using a vibration analysis model of the tube group and the support member; a probability computation step of computing the probability that a reaction force of greater than or equal to the set pressing force will occur on the basis of the computed probability density function; and an evaluation step of evaluating the set pressing force on the basis of the computed probability.
