Abstract

The invention discloses a device for analyzing stress conditions of a test model in a circulating water channel. The device comprises a hanger, a junction box, a pair of guide shafts, a base, and a five-component balance device. The upper ends of the guide shafts are mounted on the lower surface of the hanger through guide shaft supports, and the lower ends of the guide shafts are mounted on the upper surface of the base. The five-component balance device is mounted on the upper surface of the base and connected with the junction box. A force transmission bar penetrating a base guide cover connecting disk is mounted at the bottom of the five-component balance device. The device is light in weight and high in response speed, allows electrical signals to be transmitted easily, allows hydrodynamic test measurement to be automated, is small in size, can be used to measure hydrodynamic force and torque acting on the full model, and can also be used to measure hydrodynamic force and torque acting on a part model or hanger-free model.

Description

technical field [0001] The invention relates to an underwater stress analyzing device, in particular to a device for analyzing the stress of a test model in a circulating water tank. Background technique [0002] Hydrodynamics is the science of the interaction of water and objects, and is one of the most important theories of nautical technology. Nowadays, the shape and performance of cruise ships, cargo ships and passenger ships are constantly improving, all of which are closely related to the development of hydrodynamics. In the design of new ships, hydrodynamics will play an increasingly important role, and hydrodynamic testing is more critical in this. [0003] The hydrodynamic balance has a history of more than 100 years. With the development of hydrodynamics and its test technology, especially in the past 30 years, various types of strain balances have been widely used in low-speed and high-speed hydrodynamics. Calibration equipment and calibration methods have also ...
