| 摘 要： | 研究反应堆控制棒水力驱动装置在冲击作用下的流固耦合动力学问题。针对系统受向上和向下冲击两种情况,以及系统不同的设计参数,采用商用软件MSC.DYTRAN计算了系统计算模型的动力学响应。计算结果表明水力驱动装置在冲击载荷下的响应与冲击方向、步进缸水柱长短有关。向下冲击比向上冲击使系统产生更大的响应;在同样的冲击下,步进缸水柱越长响应幅值越大。此分析结果可用来评估系统的抗冲击能力。

| Abstract: | The fluid-solid coupling dynamics of a hydraulic drive for a reactor control rod were analyzed to evaluate its response with impact load. The dynamic system responses for upwards and downwards impacts with various structural parameters using the commercial software MSC. DYTRAN. The results showed that the response amplitude of the hydraulic drive depended on the direction of the impact and the water column length with longer water column resulting in larger response amplitudes. The responses for downwards impacts were larger than for upwards impacts. The analysis can be used to evaluate the system shock resistance system. |
