Device for measuring hydrodynamic force interference among multiple ships

A device for measuring hydrodynamic force interference among multiple ships comprises two vertical first guide rails and a vertical second guide rail which are fixedly installed on a trailer. A dragging mechanism with a first ship model crosses the two first guide rails, and a dragging mechanism with a second ship model is arranged on the second guide rail. A transverse moving mechanism driven by a ball screw pair, a rotation moving mechanism driven by a worm gear and a lifting mechanism are arranged on the dragging mechanism of the first ship model and are used for driving the first ship model to conduct transverse movement, rotating movement and lifting movement. The dragging mechanism of the second ship model comprises a vertical moving mechanism and a lifting mechanism which are driven by the motor and are used for driving the second ship model to conduct vertical movement and lifting movement on the guide rail. The two dragging mechanisms are both provided with a sensor for measuring the hydrodynamic force performance. The device can achieve measurement of the hydrodynamic performance when multiple ships sail at different relative positions at identical speed or different speeds and is used for comprehensive study of hydrodynamic force interference among the multiple ships.
