          摘要 針對現有檢測裝置與方法普遍存在形變適應性欠佳、檢測精度不足等突出問題,融合形變自適應機構與串并混聯測量機構,設計了一款新型核燃料棒變形檢測裝置,旨在利用形變自適應機構四自由度被動調整解決裝置與變形燃料棒緊密貼合問題,通過構建串聯檢測、并聯校正閉環測量回路,實現誤差動態補償.在此基礎上引入基于類撓度變換的微量鉸接間隙補償機制,提出一種用于抑制機械間隙干擾的測量誤差協同補償方法.樣機測量試驗結果表明裝置可自適應貼合各向隨機變形核燃料棒,配合提出的補償方法能夠實現核燃料棒高精度變形檢測.

          Abstract Limited by the difficulties of detection mechanism and error compensation,the existing detection devices and methods generally have some problems such as poor deformation adaptability and detection accuracy.Therefore,a new nuclear fuel rod deformation detection device was designed by fusing the deformation adaptive mechanism and the serial-parallel hybrid measurement mechanism.It aims to solve the problem of tight fit between the device and the deformed fuel rod by using the 4-DOF passive adjustment of the deformation adaptive mechanism,and to realize the dynamic error compensation by constructing the closed loop of serial measurement and parallel correction.On this basis,a micro articulated clearance compensation mechanism based on similar deflection transformation was introduced,and a measurement error cooperative compensation method for suppressing mechanical clearance interference was proposed.The experimental results show that the device can adaptively fit the randomly deformed nuclear fuel rods in all directions,which can realize the high precision deformation detection of the nuclear fuel rods with the proposed compensation method.
