Abstract

A hydrodynamic test model transverse moment measuring device comprises a pair of fixed connection plates (1), a connection steel rope guide pulley (2), an unloading unit fixing shaft (3), an unloading weight (4), an unloading unit sliding seat (5), a supporting unit fixing shaft (6), a supporting unit sliding seat (7), a supporting spindle (8), a supporting spindle guide (9), a right-angle adapter seat (10), a pitching direction rotating bracket (11), a cross connection shaft (12), a transverse direction rotating bracket (13), a transverse angle adjustment sheet (14) and a six-component measuring balance (15). The hydrodynamic test model transverse moment measuring device has the advantages that a model can freely move in the pitching direction in a hydrodynamic test, a needed transverse angle can be kept, the blank of a water test model transverse moment measuring measure in a towing tank is filled in, the transverse moment of a zero-speed model can be measured, and the transverse moment of a high-speed model can also be measured.

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...
