摘要
试图对池式快堆结构作较大简化,使计算简图既能反应堆结构的动力特性,又能使计算简便可行。从而把一个复杂的结构用一个简单的弹簧-质量体系来近似地等效代替。引入容器的变形假设和确定的液动压力假设,应用虚位移原理可获得体系在水平地震作用下的运动方程,而后考察其地震动响应。
The structure of pool-type fast breeder reactor (FBR) is quite simplified in order that the calculation model may both be reflecting the structural dynamic characteristics and convenient to compute it. A simple spring-mass system could be approximatively in effect replacing a complex structure. The vessel deformation and appointed dynamic fluid pressure suppositions are taken. The motion equation of the system under horizontal seismic ground motion can be obtained by means of virtual displacement principle. Finally,the seismic response of the structure is computed.
