摘　　要：在中国先进研究堆(CARR)调试试验期间,发现控制棒驱动机构在反向过程中存在驱动线圈与控制棒运动不同步的现象。为掌握控制棒驱动机构的反向性能参数,在主冷却剂系统运行条件下进行了控制棒驱动机构动态反向性能测试试验。试验数据和分析结果表明:驱动线圈与控制棒运动不同步是磁悬浮式控制棒驱动机构固有特性;棒位、棒速和驱动线圈通电电流大小等因素对动态条件下反向性能影响不大,且4组驱动机构动态条件下反向性能具有一致性;动态反向性能优于静态,是由控制棒驱动机构电磁力分布决定的。During the commissioning phase of China Advanced Research Reactor （CARR）, the asynchronism was found between drive coils and control rod when the control rod drive mechanism （CRDM） taking inversion. With the aim of acquiring inversion performance of the CRDM, a CRDM inversion performance test was taken under the condition of static coolant. The result of test shows that asynchronism between drive coils and control rod is the intrinsic characteristic of magnetic suspension CRDM; the factors, such as control rod position, control rod speed and drive coil current, have limited influence on static coolant inversion performance, and the inversion performance of four groups CRDM have uniformity under static coolant condition; the distribution of electromagnetic determines that the dynamic inversion performance is better than static inversion performance.
