Problems solved by technology

Existing laboratory test equipment cannot meet the requirements of simulating the external force exerted by real sea wind and waves on piles, and the test equipment is not easy to operate, and the frequency and amplitude of cyclic load cannot be adjusted according to time. Therefore, it is necessary to design a dynamic loading test device for sea wind and waves to meet the requirements of pipe pile tests under simulated offshore wind and waves

Abstract

The invention belongs to the technical field of marine testing, and relates to a sea wind wave dynamic load test device and method. A model box is arranged in the middle of a base. Four reaction forcecolumns are vertically arranged at four corners of the base. A horizontal circular track is arranged among four reaction force columns. Pulleys of a sliding block are fixed on the horizontal circulartrack. One end of a frequency conversion motor is connected with a servo load system, and the other end is fixed on the sliding block. A servo motor is fixed on the sliding block. An oil pump is connected with the servo motor. A servo load controller is arranged on one side of the base and is connected with the oil pump. An information transmitter is connected with a control system and an information processor through data lines. The information processor is connected with a six-degree-of-freedom information collector through a data line. The six-degree-of-freedom information collector is arranged in the middle of the horizontal circular track. The sea wind wave dynamic load test device has the advantages of simple structure, easy operation, high degree of automation, safety, reliabilityand quick test, and is free of manual assistance.

Description

Technical field: [0001] The invention belongs to the technical field of marine experiments, and relates to a device and method for a dynamic loading test of sea wind and waves. Background technique: [0002] With the rapid development of modern science and technology, my country's increasingly stringent environmental protection standards and changes in energy structure, marine engineering will show explosive growth. Offshore and coastal projects such as cross-sea bridges, offshore oil field exploitation, and offshore wind power generation are developing rapidly. Pile foundation is one of the most important foundation forms used in offshore engineering and coastal engineering. On the premise of ensuring the safety and reliability of pile foundation, the requirements for shortening construction period, saving project cost, prolonging service life and reducing maintenance work are constantly increasing. At present, most of the offshore pile foundations are large-diameter open p...
