摘　　要：针对核主泵脱落式飞轮脱落冲击造成的二次事故问题,设计了有支撑的分离式飞轮原理样机,飞轮盘在有支撑的条件下进行转动,完全依靠自身的离心力作用实现分离,消除了脱落时飞轮盘的冲击力。为对支撑条件下分离式飞轮的脱离性能进行研究,对分离式飞轮进行了受力分析并建立了力学模型,搭建了飞轮试验平台,完成了支撑条件下的分离试验。多次试验证明:分离式飞轮工作过程中,飞轮盘与轴套间的过盈量、飞轮盘的重力以及支撑位置和摩擦力、飞轮盘装配误差等因素不同程度的影响了飞轮盘的分离。从而为工程样机的试制提供了理论与试验依据。Aiming at the problem of secondary accidents may be caused by crash while the nuclear main pump fall-off flywheel falling,the prototype of separated flywheel is designed. The flywheel rotates under the supporting conditions and achieves separation,depending totally on its centrifugal force. It removes the force caused by crash while flywheel falling. To study the performance of separated flywheel under the supporting conditions,stress analysis of the separated flywheel is finished,and the mechanical model and test platform is established. Flywheel separating test is completed under the supporting conditions. The results of test show that the amount of interference between flywheel and bushing,gravity of flywheel,positions of supporting points,friction and assembling error may influence separation of the flywheel. It provides theory and testing basis for trial-producing the engineering sample.
