屏蔽式主泵飞轮方案论证及转子轴系动态性能敏感性分析

Demonstration of Flywheel Scheme and Sensitivity Analysis of Bearing Water Film Stiffness on Rotor Dynamic Characteristics of RCP

为保证核电主泵满足反应堆停堆和断电事故后惰转时间的要求,对屏蔽式主泵机组的转动惯量要求、飞轮配重方案以及主泵转子轴系的动态性能进行分析,给出了飞轮方案,并进行轴承水膜刚度对转子轴系动态性能影响的敏感性分析。

In order to ensure that the main coolant pump(RCP) meets the requirements of half flow time after reactor shutdown and power accident,the moment of inertia of the RCP,whether need to add the flywheel and the RCP rotor's dynamic performance are analyzed in this paper.Demonstration of flywheel scheme and sensitivity analysis of bearing water film stiffness on the rotor dynamic characteristics are presented.
