측정된 마모 깊이와 시간에 의해 역으로 계산된 마모상수를 이용한 마모 깊이 예측
A Method to Predict Wear Depth Using Inversely Calculated Wear Constants from Known Wear Depth and Time
초록
The wear of steam generator tubes is due to the vibration occurred between tubes and tube supporters. To predict the future wear depth, the wear constants of the impact and the sliding model is used. The wear constants, 3C/2 and K/3H, are found inversely from known wear depth and time. Using these constants, the future wear depths are found from two bodies that deform the elliptical shape. The results are compared with the measured wear depth of steam generator tubes in a nuclear power plant. The results show that the predicted wear depth envelopes the measured wear depth.
