摘　　要：脉冲堆堆芯结构类似于圆柱形刚性块体,由一铝质支撑简体支承。根据结构特点,我们分别采用刚体模型和有限元模型进行了响应分析,并将其结果作了比较。动态特性实验研究表明,分析结果是可靠的,采用刚体模型处理脉冲堆堆芯结构这种类型的结构是一种行之有效的方法。最后对关键部位作出了安全评价。The pulsed reactor core structure is similar to a cylindrical rigid body, and it is supported by a aluminum cylinder. According to the structural property, the seismic response is calculated by rigid model and finite elements model, and the results of the two models are compared.The dynamic characters (natural frequencies and critical damping ratio)are also given by experimental research. It is shown that the analytical results are reliable and the rigid model is a feasible method for the pulsed reactor core structure-like. At last the safety is evaluated for important components.
