| 6. | Aimed at the rotor bearing system of 300 mw steam turbogenerator set and on the basis of establishing its concentrated general model with 8 supportings and 9 nodes , a study was carried out on the bending vibration response of the most left end surface of shafting and of the right end face of generator 摘要针对300mw汽轮机组转子轴承系统,在建立其8支承9节点集总模型的基础上,对轴系最左端面和发电机右端面的弯曲振动响应进行研究。 |
| 7. | Fist ly , use mass equivalent method to predigest the original rotor system . secondly , use transfer matrix arithmetic to have finished the relative program to calculate the critical speed of flexible multi - tray rotor bearing system by matlab language . thirdly . finish program the unbalance response using riccati - transfer matrix arithmetic and finity buck arithmetic . fourthly , answer to the high vibration of uncontroled system when cross the critical speed , come out to adopt changing clearance damper bearing to control the viberation 本文对多柔盘转子-支承系统的振动现象做了以下初步探索:用质量离散化方法把原转子系统简化;采用matlab语言编制了对传递矩阵法计算多柔盘转子-支承系统的临界转速;用matlab语言对riccati传递矩阵法和有限元法编制了程序计算系统的不平衡响应;并针对其过临界转速时振动较大的现象,提出采用变间隙控制油膜刚度和阻尼,从而使原系统的在特定转速(临界转速)的一段范围内不平衡响应减小;并从被动控制与主动控制两方面进行数值仿真,取的了较好的控制效果。 |
| 8. | But the development of modern control theory and technology of computer and meterage change the people " s long notion of passive control and vibration reducing on rotating machanism . that is using modern control theory to active control the rotor bearing system . and then to change the design technique radically as to abstain the vibration accident 现代控制理论和计算机技术与测量技术的发展,改变了人们长期对旋转机械被动隔振和减振的观念,即用现代控制论的思想,对转子-支承系统的振动主动的进行控制,从而在根本上改变设计方法,有效地避免振动事故。 |
