A combined modular underwater test model of glass fiber reinforced plastic metal cabin

Abstract

The invention relates to a glass fiber reinforced plastic metal cabin section combined modular underwater test model. The model comprises three modules including a head glass fiber reinforced plasticcabin section, a metal sealed cabin section and a tail glass fiber reinforced plastic cabin section. The metal sealed cabin section is arranged in the middle, and the head glass fiber reinforced plastic cabin section and the tail glass fiber reinforced plastic cabin section are installed at the two ends of the metal sealed cabin section through a head glass fiber reinforced plastic cabin section flange plate and a tail glass fiber reinforced plastic cabin section flange plate respectively; and a modularized segmented design is adopted, and the head glass fiber reinforced plastic cabin section,the tail glass fiber reinforced plastic cabin section and the metal sealed cabin section are combined into an integral underwater model. The metal sealed cabin section replaces a balance sealing box,the metal sealed cabin section is also a part of a boundary dimension of the model, the model design is suitable for an underwater model with a limited dimension and is also suitable for the underwater model with an unlimited dimension, and an application range of the model is greatly improved.

Description

technical field [0001] The invention relates to the technical field of underwater test models, in particular to a combined modular underwater test model of glass fiber reinforced plastic and metal cabins. Background technique [0002] Maneuverability is one of the important performances of ships or submersibles, and it is of great significance to ensure navigation safety and improve economy. In the design stage of a ship or submersible, it is particularly important to accurately predict its maneuverability for subsequent analysis and improvement of maneuverability. [0003] The restraint model test is currently the most widely used method to obtain the maneuverability of a ship or submersible, and it is also considered to be one of the most effective methods. During the test, mandatory constraints are added to the test model through mechanical equipment, and the test model is forced to perform prescribed movements, such as linear motion and rotary motion. Superimpose one o...

Problems solved by technology

However, some underwater models cannot install a balance sealing box inside the model due to size limitations. The traditional model design cannot meet the test requirements. It is necessary to carry out an overall sealing design for a certain cabin section of the model to replace the function of the balance sealing box to achieve installation. The purpose of a force balance
