Problems solved by technology

[0004] In the prior art, the standard ship model test is the main means to verify the correctness of the wave load measuring beam system. The disadvantage of this method is that different standard ship model structures need to be designed for different measuring beam systems to ensure that the standard ship model is consistent with the wave load. The matching of the load measuring beam system, especially in the design and manufacture of ship models for different measuring systems, has high economic costs and long design cycles, resulting in slow verification of the measuring beam system and low test efficiency

Embodiment 1

[0039] Example 1: A single circular tube wave load measuring beam system is installed on a standard ship model

[0040] Such as image 3 and Figure 4 As shown, the supporting structure is a horizontal beam 24, and the two ends of the horizontal beam 24 are respectively equipped with connecting devices 22, and the connecting device 22 fixes the horizontal beam 24 between the two symmetrical end beams 16 through fasteners 223 A circular tube 26 is installed on the top of multiple horizontal beams 24 through fasteners 3 25 to realize the installation of a single circular tube wave load measuring beam system on a standard ship model.

[0041] Such as Figure 5 As shown, the structure of a single connection device 22 is: it includes two U-shaped bodies 2201 oppositely arranged, and holes 2202 are opened on the two side walls of the U-shaped body 2201, and the ends where the horizontal beam 24 and the end beam 16 are connected to each other are located at The interior of the two...

Embodiment 2

[0042] Embodiment 2: The double-tube wave load measuring beam system is installed on a standard ship model

[0043] Like the horizontal beam 24 in the first embodiment, the tops of multiple horizontal beams 24 are jointly installed with two round pipes 26 through fasteners 3 25 to realize the installation of the double round pipe wave load measuring beam system on the standard ship model.

Embodiment 3

[0044] Embodiment 3: The new U-shaped ABSPC material wave load measuring beam system is installed on the standard ship model

[0045] Such as Figure 6As shown, the end beam 16 is equipped with an L-shaped connecting block 29 and a backing plate 30 through a fastener four 27, and the connecting block 29 and the backing plate 30 are respectively located on the top surface and the bottom surface of the end beam 16; two symmetrical The connecting block 29 and the backing plate 30 on the end beam 16 form a supporting structure, and a measuring beam 28 is installed between the two symmetrical end beams 16, and the measuring beam 28, the connecting block 29 and the backing plate 30 are respectively passed through fasteners Five 31 connection, to realize the installation of the new U-shaped ABSPC material wave load measuring beam system on the standard ship model.

[0046] Such as Figure 7 As shown, the hull 100 includes a keel 1001 that runs through its longitudinal section. A pl...

Abstract

The invention relates to a standard ship model suitable for various measurement systems, which comprises a stern and a bow distributed at two ends, together with multiple sections of the hull to form a hull; Extending from the bow to the stern; a plurality of end beams arranged at intervals are symmetrically installed on the inner walls of both sides of the hull below the deck, and a support structure is installed between the two symmetrical end beams, and the measurement system is installed on multiple support structures; The motor is installed on the inner bottom of the stern, the end of the paddle shaft at the output end of the motor passes through the ship wall and the propeller is installed at the end, and the center of the outer surface of the propeller is installed with a diversion cap; the end of the stern is installed with a steering gear, and the bottom of the steering gear is installed with a rudder stock , the end of the rudder stock goes out of the ship wall downwards and the rudder is installed at the end; the gyroscope is installed on the inner bottom surface at the center of gravity of the ship; the present invention realizes the replacement of multiple different types of measuring beam systems by adjusting the supporting structure and corresponding components, and then The verification period is greatly shortened, the cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ship tank model test equipment, in particular to a standard ship model suitable for various measurement systems. Background technique [0002] When carrying out wave load model tests on ships, it is necessary to perform reasonable equivalence of the structural stiffness of the real ship according to the scale ratio according to the seakeeping tank and corresponding equipment conditions, and design a reasonable wave load measuring beam system accordingly. The rationality and standardization of the design of the measuring beam system are the key to the success of the wave load model test. [0003] There are many different types of wave load measuring beam systems, and three of them are usually used, namely: single circular tube wave load measuring beam system, double circular tube wave load measuring beam system and new U-shaped ABSPC material wave load measuring beam system . [0004] In the prior art, t...
