Problems solved by technology

[0003] At present, when conducting ship wave load tests, the speed of the ship model is usually achieved in two ways. One is that the ship model realizes self-propelled by its own power. In the self-propelled mode, it is necessary to equip the ship model with a drive motor, Transmission devices, propellers, rudders, rudder gyro and other devices, these devices not only make the structure of the ship model complicated, but also because the segmented ship model is used in the wave load test, each segment of the ship model is connected by a longitudinal Beam connecti

Abstract

The invention discloses a towing device. The invention belongs to the technical field of ship wave load measurement. The device comprises a towing bracket in fixed connection with a ship model; two first pulling ropes, wherein one end of each first pulling rope is connected with one free end of the towing bracket through a connecting device; and two second pulling ropes, wherein one end of each second pulling rope is connected with the other end of the corresponding first pulling rope through a tension sensor, and the tension sensors are used for measuring tension between the first pulling ropes and the second pulling ropes; two fixing devices connected with the other ends of the second pulling ropes respectively. The towing device has the beneficial effects that the towing device is provided for assisting in measuring the wave load borne by the typical cross section of the ship body at the navigational speed, installation is convenient, and the towing device can be used in all waves directions.

Description

technical field [0001] The invention relates to the technical field of ship wave load measurement, in particular to a towing device. Background technique [0002] Wave loading, also commonly referred to as wave force, is the action of waves on structures in the ocean. Wave loads are caused by the relative motion between wave water particles and structures. Wave is a kind of random motion, which is difficult to describe accurately mathematically, so the wave force is usually determined through physical model tests. In the process of shipbuilding, the accurate measurement of the wave load of the ship at a certain speed is very important for the rational design of the hull structure. [0003] At present, when conducting ship wave load tests, the speed of the ship model is usually achieved in two ways. One is that the ship model realizes self-propelled by its own power. In the self-propelled mode, it is necessary to equip the ship model with a drive motor, Transmission device...
