Problems solved by technology

[0005] The purpose of the present invention is to provide a vortex-induced vibration test device for marine umbilical cables to solve the problem that the existing vortex-induced vibration test device proposed in the background technology above generally has a fixed installation angle of the cable, and it is difficult to adjust the installation angle of the cable. Large and complex adjustment, it is necessary to conduct multiple tests on the cable at different angles during the test, but it is difficult to ensure that the basic parameters of each test can be consistent due to multiple tests, and it is difficult to achieve a good comparison effect. At the same time, the existing When the vortex induced vibration test device is installed on the cable, the operation is complicated, which affects the test efficiency

Abstract

The invention discloses a vortex-induced vibration test device for marine umbilical cables, relates to the technical field of test devices, and solves the problem that in the existing vortex-induced vibration test device, the installation angle of the general cable is fixed, the adjustment is complicated, and it is difficult to achieve a good contrast effect. At the same time, when the existing vortex-induced vibration test device is installed on the cable, the operation is complicated, which affects the test efficiency, including the support frame; the right side of the top of the support frame is fixed with multiple sets of the tightness adjustment motors; the support The bottom right side of the frame is fixedly connected with multiple groups of the winches; the top left side of the support frame is fixedly connected with multiple groups of the tilt adjustment motors; the upper left end surface of the support frame is axially connected with multiple groups of the tilt drive shafts . The device can realize quick disassembly of cables, is simple to use and is convenient to operate, and can fix cables of different thicknesses to improve adaptability.

Description

technical field [0001] The invention relates to the technical field of test devices, in particular to a vortex-induced vibration test device for marine umbilical cables. Background technique [0002] For structures with cylindrical cross-sections commonly used in marine engineering, ocean currents will generate pulsating pressure on the column that changes periodically in the direction of flow and cross-flow. If the column is elastically supported at this time, or the flexible pipe allows elastic Deformation, then the pulsating fluid force will cause the periodic vibration of the column (pipe), which in turn will change the flow direction of the ocean current and the influence of the ocean current on the column. This fluid interacts with the structure. The problem of the action is called "vortex-induced vibration". The main reason for the failure of marine pipelines is affected by vortex-induced vibration. Therefore, in the design of umbilical cables, it is necessary to test...
