脉冲堆驱动线抗震分析

脉冲堆驱动线结构大多为细柔部件,且对其传动功能的要求较高。因此,首先将堆桥及整个驱动线作为一个完整的力学模型进行分析,其次分析各个子结构。并将计算结果与实验结果作了比较,表明分析的结果是可靠的,证明子结构法是一种简便实用、行之有效的分析方法。最后用响应谱法的结果对关键部位作出了初步地震安全评价。

Aseismic Analysis of the Driving System for the Pulsed Reactor

The driving system of the pulsed reactor contains control rods, pulsing rod and sample rack.They are slender, and their drive function was required more strictly. First, a complete model which contains all driving system and reactor bridge was used. Then the substructure models were adopted. The results of calculation were compared with the experimental results. It shows that the analysis results are reliable and the substructure method is simple,available and utility. At last, the seismic safety was evaluated by the results from response Spectra method.
