摘要
从单圆盘转子系统的不平衡响应出发 ,提出了转子系统的激振 -固有频率干涉模型 ,建立了单圆盘转子系统不平衡响应可靠性计算理论 ,分析了设计参数对单圆盘转子系统动力可靠度影响的灵敏度 ,使得有可能在设计阶段估计转子系统不发生共振的可靠度。
From the dynamic response of a single-rotor system, an interference model of exciting frequency and natural frequency is developed. The reliability estimation theory of a single-rotor system is established. The dynamic sensitivities relating to every parameters of a single-rotor system are analyzed. The above mentioned results make it possible to estimate and effectively improve the dynamic reliability of single-rotor systems in the design period.
