摘要
提出了核电站控制棒及驱动系统的力学模型及控制棒下落时间的计算方法 ,用显式差分格式计算各构件水平动力反应 ,并考虑了二维和多点激励。计算结果表明 :本文方法的计算结果与实验结果吻合得较好。
The analysis models for control rod and its drive mechanism in the nuclear power plant are established, and a method for computing control rod drop time is presented. In the paper, horizontal dynamic responses for all the various members under multi-support and 2 components seismic excitation are solved with the explicit difference technique. A calculation in an example shows that the result obtained by this method is very good agreement with the experimental result.
