Abstract

The invention relates to a calibration device for a test measuring beam of the wave load of a ship. The calibration device comprises two loading support stools arranged separately, a support is arranged on the loading support stools, the measuring beam is arranged in the support, the two ends of the measuring beam are sleeved by loading frames respectively, and counterweights are applied to the bottoms of the loading frames. The calibration device is compact and reasonable in structure and convenient to operate; via the special-purposed calibration device, vertical and horizontal inertial moments and torque can be obtained convenient and rapidly and are similar to those of a practical ship, and it can be ensured that the torsional center is similar to that of the practical ship; and the calibration device can calibration relation between strains of different measuring profiles of the test measuring bean and the wave loads born by a profile of a hull.

Description

technical field [0001] The invention relates to the technical field of ship model wave load testing and testing, in particular to a measuring beam calibration device for ship wave load testing. Background technique [0002] When a ship performs a wave load model test in a seakeeping tank, in order to simulate the geometric characteristics of the ship itself and measure the load of each section, it is necessary to use a segmented model connected by a measuring beam for the wave load model test. At present, relevant research can only carry out the similarity of vertical or horizontal characteristics, or use circular tubes for pure torque simulation. Aiming at the above-mentioned shortcomings, the present invention designs a cross-sectional structure form of the measuring beam that can simultaneously perform vertical and horizontal stiffness, torsional stiffness and torsion center similar to that of a real ship, and provides the calibration method and calibration of this type o...
