The invention provides a test device for simulating variable-curvature wear of a grounding section of a dynamic cable and a rock seabed, which belongs to the field of marine equipment testing and comprises a weight, a clamp, a cable, aggregate and a connecting piece which are positioned in a container, and an actuator and a tripod which are positioned outside the container. The container is used for accommodating water and aggregate to simulate a marine environment; the cable is fixed on the bottom surface of the container through a clamp and contacts with aggregate to cause abrasion, the top of the clamp is provided with a weight for controlling the contact pressure of the cable, the side surface of the clamp is connected with an actuator through a connecting piece for controlling the displacement of the dynamic cable, and the actuator is fixed through a tripod. According to the invention, the contact pressure of the dynamic cable is regulated and controlled by adjusting the weight of the weight, the movemen
