Description

technical field [0001] The invention relates to an anchor chain dynamic characteristic tracking device and method, belonging to the field of anchor chain testing. Background technique [0002] As the development of the ocean goes deeper and deeper, the ship will be affected by the nonlinear disaster environment at different time and space scales, and it will experience large-scale motion, large-scale deformation, high-modal dynamic response, corrosion and decay, etc. serious security threat. Therefore, in order to fully guarantee the safety of the ship, various factors must be considered comprehensively and studied by various means. In recent years, guyline mooring systems have been the most commonly used type of anchor chain. At present, the deformation and tension measurement of deep-sea anchor chains is limited to numerical simulation or experimental measurement. In the experimental measurement, the accurate ocean environment cannot be simulated, and the method of cutti...

AI Technical Summary

Problems solved by technology

At present, the deformation and tension measurement of deep-sea anchor chains is limited to numerical simulation or experimental measurement. In the experimental measurement, the accurate ocean environment cannot be simulated, and the method of cutting off the anchor chain is generally used for measurement, which is difficult to reflect the real ocean conditions.

Moreover, there is currently only a device for measuring the tension of the cable through a tensiometer, but there is no device for tracking and measuring the direction of the cable in real time.
