控制棒水力驱动系统在摇摆工况下的运行特性

Kinematics characters of a hydraulic driving system of control rods under rocking

通过由控制棒水力驱动系统实验本体、六自由度船舶运动模拟器及测量与控制系统组成的实验装置，进行了实验本体随模拟器摇摆时控制棒的步升、步降及全程快速落棒实验，还进行了实验本体横倾４５°静态下的快速落棒实验，取得了一系列实验数据。实验结果表明：控制棒水力驱动系统在摇摆角达３５°，周期为１０ｓ时仍具有良好的运行可靠性和固有安全性；在横倾４５°时仍能靠重力顺利落棒。因而该系统经过适当改进后可以满足摇摆工况下要求，为该系统应用于船用核动力堆提供了实验依据。

The experimental equipment consist of the test object of the hydraulic driving system of control rod (HDSCR), 6 freedom rocking test plate, measure system and control system, which was used to study kinematic characters of HDSCR under rocking. By using this equipment, several experiments were made when the test object followed the rocking test plate to rock: 1) the control rod lifted or fell step by step; 2) the control rod fast fell by gravity. Also, the experiment of control rod fast falling was made when the test object bending angle was 45°. Experimental results indicate: 1) HDSCR has favourable moving reliability and inherent safety when rocking angle is less than 35°; 2) the control rod can fall smoothly by gravity when bending angle is 45°. This system can be satisfied with ship rocking requirements when it will be appropriatly changed. This research will provide experimental basis for HDSCR to be used in the ship power reactors.
