Abstract

The invention relates to the technical field of ship and ocean engineering professional ship models, in particular to a constant tension device for large-opening model test of a river-to-sea ship. Theconstant tension device for large-opening model test of the river-to-sea ship comprises a pressure plate, a transitional panel, a sliding loading shaft, a loading shaft slide groove, a steel wire rope, a tension sensor, an electric motor sliding plate, an electric motor, a supporting platform, an electric motor slide groove, a rectangular connecting plate, a U-shaped connecting plate, a controller and a tension balancing device. According to the constant tension device for the large-opening model test of the river-to-sea ship, the load simulation of outboard water pressure is increased in themodel test by analyzing the characteristic of a wide and flat ship model of the river-to-sea ship and a data signal of the tension sensor is monitored to adjust the torque, output by the motor, in real time by using a control program; therefore, the constancy of the tension applied to a side shell by using the steel wire rope is guaranteed so that the test process is more appropriate for the actual situation and the test result is more persuasive.

Description

technical field

[0001] The invention relates to the technical field of professional ship models of ships and marine engineering, in particular to a constant tension device used for large opening model tests of river-sea direct ships. Background technique

[0002] The ultimate strength of the hull structure is an important index to reasonably and accurately evaluate and ensure the safety and reliability of the hull structure. Since the concept of the ultimate strength of the hull structure was proposed, the importance of the ultimate strength of the hull structure is increasing day by day in view of the fact that the true prediction of the ultimate strength plays a decisive role in ensuring the safety and reliability of the hull structure in the ultimate state , has become the focus and hotspot in the field of ship research in recent decades. So far, great progress has been made in how to accurately predict the ultimate strength of the hull structure, and several systematic r...
