Abstract
Lining life numerical evaluation is getting increasingly popular. Through numerical simulation, the impacts on lining life due to design changes can be easily evaluated. The numerical approach usually predicts rotor temperature first, and then uses the lining wear versus rotor temperature data derived from physical testing to further assess lining life. Therefore, the success in predicting lining life largely relies on the accuracy of predicted rotor temperature as well as the lining wear versus rotor temperature data incorporated afterwards.
In this paper, a 1-D rotor thermal model is presented, which intends to better predict rotor temperature while not dramatically increasing computational time. Furthermore, the inputs that would greatly affect simulation results are discussed. After that, two lining life evaluation examples, which employ the 1-D rotor thermal model, are presented. Finally, the applicability of lining wear versus rotor temperature data is discussed.
