Abstract

A device for measuring heeling moment of a hydrodynamic test model, including a pair of fixed connecting plates (1), a cable guide pulley (2), a fixed shaft of an unloading unit (3), an unloading weight (4), and a sliding seat of an unloading unit (5), support unit fixed shaft (6), support unit sliding seat (7), support main shaft (8), support shaft guide device, right-angle adapter seat (10), pitch direction rotation support (11), cross connection Shaft (12), heel direction rotation support (13), heel angle adjustment piece (14) and six-component force measuring balance (15), the advantages of the present invention are: 1, the model can be pitched during the hydrodynamic test It can move freely in the direction and maintain the required heel angle at the same time, which fills the gap in the measurement method of the heeling moment of the water surface test model in the towed pool; the device can measure the heeling moment of the model at no speed, and can also measure the height The heeling moment of the model at ship speed.

Description

technical field [0001] The invention relates to the field of hydrodynamic tests of ships, seaplanes, etc., in particular to a measuring device for heeling moment of a hydrodynamic test model. Background technique [0002] Most of the hydrodynamic tests of ships and seaplanes are carried out in the towed pool. During the test, the degree of freedom of the model's heeling direction is limited, so that the heeling moment of the model cannot be measured during the movement. However, real ships and aircrafts may have heeling during the water surface sliding process, especially some unmanned combat platforms have higher requirements for their anti-overturning performance, and the demand for measuring the heeling moment of the model in the hydrodynamic test is increasing. more urgent. Contents of the invention [0003] The object of the present invention is to provide a heeling moment measuring device for the problem that the heeling moment cannot be measured in the current towi...
