Description

technical field [0001] The invention relates to a measuring device and a using method thereof, in particular to an environmental load measuring device of an ocean engineering model and a using method thereof. Background technique [0002] The deep-sea platform system is complex in technology, large in investment, and high in risk. Its stress situation is an important basis for designing the offshore platform structure and its moorings, risers and other related systems. Therefore, it is very important to correctly obtain its stress situation in harsh ocean environments. important. When designing the load of the deep-sea platform system, the most reliable method at present is to simulate the actual working conditions of the deep-sea platform system through physical model tests, obtain the load measurement results, and use this as the ultimate basis for designing and building offshore platforms . In the prior art, physical model tests of offshore platforms are carried out in ...

[0005] 2. When measuring the second-order wave force in the case of oblique waves, the spring and the semi-submersible platform model cannot be kept in a straight line due to the effect of the wave force, which makes the error of the measured results of the sensor very large and cannot be applied to the analysis and calculation.

[0006] 3. Every time the measurement angle is changed, the bracket and the spring connected with the sensor need to be moved and disassembled. Since the operation is carried out in the pool by boat, the accuracy is usually not achieved, and the workload is heavy
