Abstract: Provided are a vertical fatigue test device for a dynamic submarine cable based on a topology optimization design framework, and a method thereof. The device includes a bending table, a main framework, the dynamic submarine cable, a connecting hinge, a supporting frame, a bottom plate, and a tension actuator; the bending table is mounted on an upper plate at a top of the main framework, and the main framework, the supporting frame, and the tension actuator are mounted on the bottom plate; an upper end of the dynamic submarine cable is connected with the bending table through a clamping mechanism; each of a left end and a right end of the bending table is connected with a bending actuator; the bending actuators are connected to the upper plate and are configured to achieve reciprocating swinging of the bending table.
