控制棒落棒性能分析是驱动线设计验证的重要部分。本文在AP1000控制棒驱动线落棒实验中,应用高速摄像仪拍摄落棒历程,并提出了一种结合数字图像相关和亚像素插值的方法,用于处理拍摄的图像。基于此种方法,获得了精确的控制棒棒位-时间、速度-时间、加速度-时间曲线,有利于验证和改进控制棒驱动线设计。
Background: Control rod drop performance is essential for safety analysis of nuclear power plant. Purpose: To validate the design of control rod drive line (CRDL)
a high-speed digital camera is used to record the control rod drop course in AP1000 CRDL drop performance experiment. Methods: The recorded video images are analyzed by a digital image processing method which includes digital image correlation and sub-pixel algorithm. Results: Based on such approach
the relationships of control rod’s position
velocity and acceleration with time are obtained. Conclusion: This approach has high accuracy theoretically and will be useful for validating and improving the design of CRDL. Abstract
