106375 - Fretting Wear Prediction of an Energy-Based Model for Heat Transfer Tube in Steam Generators 

The heat transfer tube of steam generators can be vibrated by the fluid, which causes impact and sliding between the heat transfer tube and the support, which can be named as fretting wear. Fretting wear is an unavoidable damage mode of heat exchanger tube bundles. In practical engineering, it is necessary to predict the wear of the heat exchanger tube, especially in steam generators. At present, the most widely-used fretting wear prediction model is the Archard model, which can not consider the effect of impact in wear process. In fact, the impact role in impact-sliding wear can not be ignored. Based on an energy method, an impact-sliding prediction model is proposed. And a finite element calculation program is established, and the prediction results of the Archard model and the energy-based model method are calculated respectively. The results show that the prediction of impact sliding wear prediction model based on energy loss can adapt to more work conditions, and is better  than Archard model in the fretting wear prediction of steam generator tube bundles. The proposed model is promising in the prediction of the fretting wear of the steam generator ,and is meanful in the safe ensurance operation of the equipment.
