中国先进研究堆（CARR）现役控制棒驱动机构在设计上存在一定缺陷，因而对该驱动机构提出了改进。改进型机构空程的设计目标为达到现役机构空程一半以内，为验证改进设计，采用控制变量法分别针对棒速、电流、摩擦力、负载等因素进行实验。实验结果表明，改进型驱动机构的空程较现役驱动机构缩小了约一半，达到了改进设计目标；并且确定了该驱动机构空程的影响因素主要是衔铁和线圈的连接刚度以及系统摩擦力。
中國先進研究堆（CARR）現役控製棒驅動機構在設計上存在一定缺陷，因而對該驅動機構提齣瞭改進。改進型機構空程的設計目標為達到現役機構空程一半以內，為驗證改進設計，採用控製變量法分彆針對棒速、電流、摩抆力、負載等因素進行實驗。實驗結果錶明，改進型驅動機構的空程較現役驅動機構縮小瞭約一半，達到瞭改進設計目標；併且確定瞭該驅動機構空程的影響因素主要是銜鐵和線圈的連接剛度以及繫統摩抆力。

There are some defects in the design of the control rod drive mechanism which is actively serving in China Advance Research Reactor (CARR). Because of the defects, a method was proposed to improve the mechanism. Theoretically, idle stroke of the improved mechanism is half of that of actively serving mechanism. To verify the improvement, experiments, which were about the influence elements like the speed of the rod, current, frictional force and the load of the mechanism, were designed with control variables method. The results showed that idle stroke were reduced about two-thirds after the improvement, which had achieved the design aim.Besides, the main influencing factors, the frictional force of the system and the coupling stiffness of armature and coil, of idle stroke were determined.
