A Method for Prediction of Tube Wear by Relative Displacement in the case of Inclined Contact between Tube & Support of Steam Generator

증기발생기에서 지지대와 세관의 경사면 접촉시 상대변위에 의한 세관 마모량 예측 방법

When the tube contacted to support and antivibration bar of the steam generator in unclear power plant, the contact area is worn out by their relative displacement. In the study, wear depths of the tube inclined to tube support and antivibration bar are approximately predicted by a method using the contact load and relative displacement. In the case of the inclined contact, the results show wear depths of the steam generator tube predicted by the impact model are larger than those by the sliding model.
