摘要
汽轮发电机基础的动力特性的研究对机组的安全稳定运行显然很重要。针对某汽轮发电机组的框架式基础运用Matlab软件建立空间有限元离散模型,采用振型叠加法分析其在简谐激励下的响应,并与相关文献数据进行了对比,对其安全性做了评价。计算结果表明动力响应曲线、频率、振幅等均满足要求,得出了一些有意义的结论。
The turbine-generator foundation plays an important role in large power plants. It＇s obvious that the study of dynamic characteristics is very important for the safe and stable operation of the turbine unit. In this paper, with Matlab the space finite element method for a certain turbine-Generator frame foundation is. The mode superposition method is used to analyse its dynamic response under, the data obtained is compared with the data and the of the turbine unit is evaluated. The calculated results indicate that the curve of the , frequency and amplitudes can satisfy all the requirements and some significative conclusions have been drawn.
