摘要
本文对池式快增殖反应堆进行较大简化,使计算简图既能反映结构的动力特性,又能使计算简便易行。文中将一个复杂的结构以一个简单的质量一弹簧体系来近似地等效代替,并引入容器的变形假设和确定的液动压力假设,应用虚位移原理建立体系在水平地震动作用下的运动方程,而后考察其动力特性。
In this paper the structure of a pool-type fast breeder reactor is simplified in orderthat the calculation model may both be reflecting the structural dynamic characteristics andconvenient to compute the reactor. So, a simple mass-spring system may approximately takethe place of a complex structure. The vessel deformation and the determinate dynamic fluid pressure assumptions are made. The virtual displacement principle is applied to establish the motion equation of the system under horizontal earthquake action. And then the dynamiccharacteristics of the vessel is examined.
