核电厂IHP通风围板的抗震设计优化
|
摘要
核电厂一体化堆顶组件(IHP)通风围板为驱动机构磁轭线圈的冷却提供了间隙均匀的通道。为了优化IHP通风围板的设计,根据ANSI/AISC N690分析了当前设计的通风围板的关键结构件在D级使用限制下的应力和变形并对关键结构件进行了初步设计优化,然后对IHP通风围板进行了有限元分析并对通风围板进行了最终设计改进。经过抗震设计优化通风围板的最大应力值分布趋于均匀。本文对抗震类设备的设计优化具有一定的参考价值。
Integrated head package(IHP) cooling baffle supplies uniform gap cooling channel for control rod drive mechanism coil stack.For optimizing design of IHP cooling baffle,stress and deformation of cooling baffle key parts were analyzed at Level D service limit according to ANSI/AISC 690,and primary optimization of key parts was processed.Then the cooling baffle was analyzed using finite element method,and final design improvement of baffle was made.The result shows better maximum stress distribution is obtained after optimization.This paper could be referenced for design optimization of seismic components.
