冲击波对核反应堆安全壳的动力响应研究

本文用时域边界积分方程提出研究半球形核反应堆安全壳在爆炸冲击波作用下动力响应分析的计算模型。从空中爆炸和地面爆炸两方面探求壳体位移和变形过程,分析冲击波在壳体内的传播规律。计算了在水平冲击波作用下壳体的内力分布,其计算结果可以作为我国核电站设计的参考分析依据。

TRANSIENT RESPONSE OF A CONTAINMENT STRUCTURE OF NUCLEAR REACTOR SUBJECTED TO A BLAST WAVE

This paper is concerned with the transient responses of semisphere containment structure of nuclear reactor to a blast wave by the boundary element method in time domain. Two cases of explosion in air and on the ground are concerned to calculate the displacement and deformation of the structure . It is analyzed that the propagation of elastic wave in the structure to a blast wave, and internal stress distribution of the shell under a horizontal blast wave is calculated in this paper. The calculating results by the present method may provide theoretical analysis basis for the design of containment structure of nuclear reactor in our country.
