Abstract

A dynamic calibration device for a test pipeline model of a pool and a calibration method thereof, including an interconnected control module, a drive module and an execution module, the control module is an industrial computer, and the drive module includes a servo motor, a servo driver and a servo motion control card. The execution module described above includes the sliding table mechanism; through the cooperation among the three modules, a test method for the dynamic characteristics of the pipeline system in the ocean engineering tank model test is established. Compared with the pure static characteristic calibration, it significantly provides the simulation of the pipeline system in the tank test Accuracy, improving the pool model test technology, using the electric motor to drive the screw to realize the simulation of the movement of the top of the pipeline, which has the advantages of high simulation accuracy, quick change of movement form, and stable structure form.

Description

technical field [0001] The invention relates to the technical field of marine engineering hydrodynamic tests, in particular to a dynamic calibration device and a calibration method for a tank test pipeline model. Background technique [0002] Theoretical calculation and tank model test are two important ways to study the hydrodynamic performance of floating mooring structures. Compared with theoretical calculations, model tests are closer to the real situation, and the resulting data are more reliable and convincing. However, in the model test, the actual operating conditions must be truly reflected and simulated to draw correct conclusions. The simulation of the force characteristics of the mooring lines is the precondition that must be realized in the whole model test. [0003] The pipeline system includes mooring cables, risers, cables and other flexible systems. The stress characteristics include static characteristics and dynamic characteristics. The static characteri...
