基于发电机扭矩的轴系快速疲劳损伤评价方法研究
Study on Fast Assessment of Shafting Fatigue Damage Based on Turbo-Generator Torque
摘要
Abstract
Based on the full-scale model analysis coupled with the basic torsional vibration analysis,a method to assess the shafting torsional vibration fatigue damage is proposed and validated by using the transient numerical analysis.The method can evaluate the damage directly by using the generator's electromagnetic torque instead of the speed measurement gear and the torsional vibration sensor.The results are consistent with those evaluated by the method adopting turbine-end torsion angle data.This method can improve the precision and accuracy of the torsional vibration fatigue damage assessment.关键词
