Problems solved by technology

However, when these towing devices are used in the towing test of ships navigating in ice regions, the resistance measurement of the ship model often results in negative values, which makes the measured ice-breaking resistance of the ship model relatively small, which seriously affects the accuracy of the test

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] combine Figure 1 to Figure 3 , the novel ice region ship model test towing device of the present invention is composed of a ship model fixing device, a balance fixing device, a traction device and a towing platform device. The ship model fixing device is mainly used to connect the ship model. The fixing device consists of three different lengths It is composed of 8080 aluminum profiles, and the aluminum profiles are arranged in three different directions. The aluminum profiles and the ship model are connected by corner fittings, and the vertical aluminum profiles can be adjusted up and down. The aluminum profiles in the vertical direction are directly connected to the balance fixing device through the connecting plate. The balance fixing device adopts two bosses with grooves to fix the force-measuring balance used in the ordin...

Abstract

The invention provides a towing device for a ship model test in an ice zone. The towing device comprises a fixing device used for being mounted on a ship model, a balance fixing device, a traction device and a towing platform, wherein the balance fixing device is used for fixing a force balance in the process of test; one end of the traction device is connected with the balance fixing device through a damping rod buffer and two tension springs, and the other end of the traction device is connected with a fixing mold frame of the towing platform through plastic-coating steel wires, the damping buffer and aluminum profiles; the fixing mold frame is fixed on a side axle of a laboratory trailer; besides, a guide rod and a fastening and lifting device control cabinet are mounted. The towing device disclosed by the invention is suitable for the towing test research for the ship model during the sailing of the ship model in the ice zone, and has stable course stability, so that hydrodynamic performance of the ship model during the sailing of the ship model in the ice zone can be more reliably measured, and the accuracy of the test is effectively improved.

Description

technical field [0001] The invention relates to the technical field of ship test towing, in particular to a ship model test towing device in an ice area. Background technique [0002] The towing device will be used when the ship model is tested in the towing pool, the ice pool and other pools, and now the existing towing device is designed for the ship model to sail in the ice-free area, usually using airworthiness instruments, solid formwork It is towed with the gravity towing mechanism and other towing devices. The towing method usually adopts rigid connection. This towing method is very practical for the ship model to sail in the ice-free area. However, when these towing devices are applied to the towing test of ships navigating in ice regions, the resistance measurement of the ship model often results in negative values, which makes the measured ice-breaking resistance of the ship model relatively small, which seriously affects the accuracy of the test. Therefore, it is...
