摘要
Abstract
The vibration response measurement results of the physical model test for turbo-generators are generally smaller than those obtained from numerical simulation analysis.To analyze the reasons for the discrepancy between the physical and numerical models,improve the accuracy and reliability of their predictions of vibration responses,this paper conducts a comparative study of the physical model test results and numerical simulation analysis results for multiple double-reheat turbo-generator foundations.The vibration evaluation system,damping model selection and the choice of numerical analysis methods are analyzed to obtain the causes of the discrepancies between the two models and propose suggestions for improving the accuracy of both models.关键词
