摘要
通过对轴系进行模化分析,将Holzer传递矩阵法应用于东方300MW汽轮发电机组轴系扭振的固有频率计算中,通过理论分析及具体算例运算,表明该方法既简便又具有较高精度,是一较为理想的汽轮发电机组轴系扭振频率计算方法。根据实际计算经验,合理地等效连续阶梯轴将给计算带来方便。
Introducing the model based on continuous mass holzer transfer matrix to the nature torsional vibration frequency calculation of Dongfang 300 MW turbo-generator set , analyzed with shaft modeling. The theory analysis and the actual example calculation indicate that this method is brief and precise. So it is a perfect calculating method of the nature torsional vibration frequency of the turbo-generator set. The experience indicates that predigesting ladder shaft will bring more convenience.
