汽轮机工业发展的要求和转子动力学的进展,使现代汽轮机设计师开始有必要研究如何设计出振动性能更好的汽轮机,以便在突然产生不平衡等情况下仍保证机组安全,或者甚至在临界转速区也能安全运行的设计方法.本文通过一种简单的模型以及一系列不平衡响应计算来分析转子结构因素对共振特性的影响,从而提出从设计上减小转子共振对不平衡量的敏感性的若干方法.
Turbine industry requirements and advances in rotor dynamics have made it imperative for modern turbine designers to study how to design turbines with better vibration performance to ensure unit safety even in the event of sudden imbalances or even at critical speeds Region is also safe to run.This paper analyzes the influence of rotor structural factors on the resonance characteristics through a simple model and a series of unbalanced response calculations and proposes to reduce the sensitivity of rotor resonance to unbalance Several ways.
