Abstract

The invention discloses a self-elevating platform wave current loading experimental data acquisition apparatus and method. The technical scheme includes a pool (1), a self-elevating platform (2), a stress strain gauge combination (3), a triaxial vibration acceleration sensor (4), an acoustic emission sensor combination (5), a wave height sensor (6), a data acquisition device (7), and a data processing display device (8). A mode for arranging a plurality of sensors at the same time is employed. Multiple groups of experiment results can be obtained after one experiment is finished, and the multiple experiment results can be mutually verified. The experiment workload is greatly reduced on the basis of guarantee of the experiment result reliability. The problem of synchronous acquisition of each sensor can be well guaranteed. All environment data in an experiment process is collected completely and once. The precision of the wave current loading experimental data acquisition is greatly improved. The problems that the error of the experimental data is large and manpower and material resources are waste in the prior wave current loading experiment are solved.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a wave and current load data acquisition device and method. Background technique [0002] In the construction of marine engineering, the sea environment is very harsh, often affected by typhoons, waves, currents, sea ice, tides and earthquakes at the same time. Offshore jack-up platforms have higher requirements for stability and environmental adaptability, their structures are complex and expensive, and it is difficult to accurately determine the external load and structural strength standards. Wave and current loads are the control loads of offshore structures, which play a very important role in the cost, safety and life of the project. Therefore, accurate wave and current load calculation and reasonable strength assessment are particularly important in the design stage of jack-up platforms. [0003] In the conventional wave-current load experiment, th...
