摘　　要：为了获得秦山核电二期工程控制棒导向组件在空气和静水中各阶模态固有频率、振型、阻尼比,并为控制驱动线抗震试验和结构动力分析(地震响应计算)提供可靠的固有特性参数,对控制棒导向组件样机(1∶1)进行了动态特性试验。本文介绍了本试验所采用的先进测量系统以及试验方法和结果。In order to get the natural frequency, mode shapes and damping of the control rod guide tube (CRGT) of Qinshan phase Ⅱ NPP project in air and water, the dynamic property test of CRGT mockup (1:1) was completed. The test results in air could be used to determine a reliable analysis model for the CRGT dynamic analysis, and could be also used to offer important parameters (natural frequencies) for the CRGT seismic test. The mode test method, measurement system and the main results were described in this paper.
