Other AbstractThe invention relates to a curvature measurement control technology, in particular to a high-precision curvature measurement control device and a method thereof. The invention calculates the included angle of neighboring strings on each equant section according to a steel material curve as a given value of a closed-cycle control system, uses a rotary encoder coaxial with a detecting wheel at the top end of a guide rod of a straight-line displacement detecting mechanism to detect the curve displacement amount moving along the steel materials, uses a transducer to detect the deformation amount of the steel materials through the guide rods on three straight-line displacement detecting mechanisms, uses the values of the three straight-line displacement detecting mechanisms to calculate the actual included angle of neighboring strings as a feedback quantity of the closed-cycle control system and uses a hydraulic servo system connected with an analog amount output card to control the deformation amount of the steel materials during a machining process. The invention can measure and control a costalis curvature with high precision and is used for continuous cold bending of a submarine and a hull costalis.
