基于核安全级固定型铅酸蓄电池组及支架抗震试验,构建了相应数学分析模型,采用反应谱有限元法和等效静力法计算了支架地震响应,并与试验数据进行了对比。结果表明,反应谱有限元计算结果相对于等效静力计算结果相对精确、合理,且有一定保守裕度。 Based on the seismic tests of the lead-acid batteries and scaffolds with nuclear safety grade, a corresponding mathematical model was constructed. The seismic response of the scaffolds was calculated by using the response spectrum finite element method and the equivalent static method, and compared with the experimental data. The results show that the results of the finite element analysis of the response spectrum are relatively accurate, reasonable and have a conservative margin relative to the equivalent static calculation results.
