概要
This paper proposes the method of estimating vibration-induced stress for the complex small-bore piping vith general piping. The method consists of the vibration m easurements and the finite element method FEM). The stresses are estimated using the FEM model optimized by the values of vibration measurements. Vibration test is performed to validate the method. As the results, the estimated stress using the second proposal method became to be from 0.5 to 2 times to the measured one. Sinc e the vibration-induced stress is Estimated easily and quickly using portable vibrometers, it can be said to use as primary screening although naving a deviation.
