【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。
[Abstract]:In view of the secondary accident caused by the shedding impact of the nuclear main pump's detached flywheel, a supported prototype of the separation flywheel is designed. The flywheel is rotated under the condition of support, and the separation is realized by the centrifugal force acting on itself. Eliminate the impact of flying wheel when shedding. In order to study the separation performance of the separation flywheel under the support condition, the force analysis and the mechanical model of the separated flywheel were carried out, and the test platform of the flywheel was set up, and the separation test under the supporting condition was completed. Several tests have proved that the interference between the flywheel and the shaft sleeve, the gravity of the disc, the supporting position and friction, and the assembly error of the flywheel affect the separation of the flywheel in different degrees. Thus, it provides theoretical and experimental basis for the trial production of engineering prototype.
