反应堆冷却剂进口管破裂时断面上流体突然失压,本文不研究流体失水喷放形成大流动和汽水分离全过程,只研究失压时吊篮与流体耦合的瞬态振动过程,对流体动力学方程线性化处理后求得吊篮结构上的响应。
When the reactor coolant inlet tube ruptures suddenly, the fluid in the cross-section suddenly loses pressure. This paper does not study the whole process of large-flow and soda-water separation due to fluid loss and water injection. Only the transient vibration process of the coupling basket and fluid coupling under loss of pressure is studied, Obtain the response of the basket structure after the linearization of equation.
