Method and device for determining structural deformation of mounting channel of control rod driving mechanism

The invention relates to a method and device for determining structural deformation of a mounting channel of a control rod driving mechanism, a terminal and a storage medium. According to the method, the top surface of a support cylinder, the top surface of a movable guide pipe, the upper surface of a component and the lower surface of the component are selected as movable connection points when the four mechanisms are connected; the distance between adjacent mechanisms of the support cylinder, the movable guide pipe and an assembly in the mounting channel and the offset of each mechanism relative to the central axis of the channel are determined, and further a first included angle and a second included angle which are used for representing the structural form after deformation are determined; therefore, through the first included angle between the support cylinder and the movable guide pipe after structural deformation and the second included angle between the movable guide pipe and the assembly after struct
