A standard ship model suitable for various measurement systems

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...

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
