The invention discloses an experimental device for simulating vortex-induced vibration of a submarine pipeline in a complex marine environment. The experimental device comprises a water tank, whereina false bottom is arranged at the bottom end in the water tank; a supporting frame is arranged at the top end of the water tank; a supporting transverse plate is arranged at the bottom end of the supporting frame; a horizontal guide rail is arranged at the bottom of the supporting transverse plate; a vertical bracket is arranged at the bottom end of the horizontal guide rail; a vertical sliding rod is arranged in the vertical bracket; L-shaped supporting arms are arranged at the bottom end of the vertical sliding rod; and an adjustable pipeline is arranged between the L-shaped supporting arms.The experimental device disclosed by the invention has the beneficial effects that the experimental device fills the blank that researchers develop a double-degree-of-freedom vortex-induced vibrationcharacteristic research of the submarine pipeline under an actual complex marine environment condition; physical model experimental working conditions under various actual complex marine environmentconditions can be conveniently realized; and a double-degree-of-freedom vortex-induced vibration experimental working condition can be realized and a single-degree-of-freedom vortex-induced vibrationexperimental working condition also can be realized through a limiting stopper, so that a double-degree-of-freedom coupling effect can be conveniently analyzed and synchronous acquisition of pipelinedynamic response, stress and streaming field data can be realized.
