Abstract

A forced reciprocating movement device of ocean structure in the technical field of ocean engineering includes: a base, a straight track, a sliding block, a driving motor and a speed reducer, whereinthe base is parallelly fixed on the bottom of a trailer, the straight track is fixedly arranged on the lower surface of the base, and the sliding block moves on the straight track by means of pinion and rack and is provided with the driving motor and a planetary speed reducer. The device can fix the ocean structure on the bottom of the sliding block, is driven to do reciprocating movement on the straight track by the driving motor and simulate the phenomena of vortex-induced vibration and vortex-induced movement, and is simple in structure and high in automation degree.

Description

technical field [0001] The invention relates to a test device in the technical field of marine engineering, in particular to a forced reciprocating motion device for marine structures. Background technique [0002] The vortex-induced motion of large-scale deep-water marine engineering structures such as semi-submersible platforms, SPAR platforms, TLP platforms, and buoys under the action of waves and currents, and the small-scale components of offshore platforms such as pile legs, anchor chains, and risers under the action of waves and currents The vortex-induced vibration under the environment is a frontier research topic in the field of ocean engineering. Like self-excited oscillation, forced oscillation simulation and experiment are also important research contents. At present, model testing is one of the most effective ways to study vortex-induced motion and vortex-induced vibration. Through model testing, the hydrodynamic coefficients of ocean engineering structures un...
