Problems solved by technology
[0002] Offshore floating equipment is the infrastructure for the development of marine resources. However, in a complex wave and current environment, under the dynamic loads of marine environments such as waves, currents, winds, and earthquakes, the vibration response of offshore floating equipment is very severe.
In related technologies, the vibration of offshore floating equipment is mainly reduced by means of vibration damping devices or by increasing the stiffness of structural components, but whether the vibration damping effect of this method is ideal needs further verification

The present application proposes a detection method and device for a vibration damping device of offshore floating equipment. The method includes: obtaining a first attribute parameter of a first offshore floating device and a second attribute parameter of a second offshore floating device, wherein the first offshore floating device is an offshore floating device with a vibration damping device, and the second The offshore floating equipment is an offshore floating equipment without a vibration damping device; the third attribute parameter of the vibration damping device is obtained; according to the first attribute parameter and the third attribute parameter, the first upper deck of the first offshore floating equipment is obtained The first displacement; according to the second attribute parameter, obtain the second displacement of the second upper deck of the second offshore floating device; compare the first displacement with the second displacement, and obtain the comparison result; in response to the comparison result failing the test, then According to the comparison results, an adjustment strategy for the vibration damping device is generated. The detection method in the present application is convenient and quick, has high accuracy, and can improve the vibration damping effect of the vibration damping device.
Description
technical field [0001] The present application relates to the field of anti-seismic technology, in particular to a detection method and device for a vibration damping device of offshore floating equipment. Background technique [0002] Offshore floating equipment is the infrastructure for the development of marine resources. However, in a complex wave and current environment, under the action of marine environmental dynamic loads such as waves, currents, wind, and earthquakes, the vibration response of offshore floating equipment is very severe. In related technologies, the vibration of offshore floating equipment is mainly reduced by means of vibration damping devices or by increasing the stiffness of structural components, but whether the vibration damping effect of this method is ideal needs further verification. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an...
