Abstract

The invention discloses a tube bundle fluid-structure interaction dynamic vibration test apparatus. The apparatus comprises a water storage tank (1), a data acquisition system (2), an experiment waterchannel (3), a water pump (4) and a tube bundle clamping bench (5), the tube bundle clamping bench (5) comprises a platform (9) fixedly arranged at the top of the experiment water channel (3), and the middle part of the platform (9) is fixedly provided with an intermediate standpipe (10) penetrating through the platform (9) and the experiment water channel (3) in sequence. The beneficial effectsof the apparatus are that the structure is compact, the position and the arrangement mode of the tube bundle can be randomly changed, and the test steps are simple; and stress-strain data is acquiredby employing a data acquisition system so that analysis bases are provided for analysis of accidents and accident reasons of the tube bundle due to flow-induced vibration.

Description

technical field [0001] The invention relates to a tube bundle fluid-solid coupling dynamic vibration test device and method. Background technique [0002] The tube bundle will cause vibration under the action of lateral flow. When the vibration frequency of the tube bundle is close to the natural frequency of the standpipe, the riser will experience a resonance phenomenon in which the vibration amplitude becomes larger, resulting in collision and friction between the standpipes. This wear causes Fatigue damage of the standpipe will shorten the service life, and in serious cases, it will cause a safety accident of the standpipe, and the leakage of the medium will cause environmental pollution. After fully understanding the force of a single standpipe in the entire tube bundle, experiments will be carried out on standpipes with different arrangements and positions to monitor their real-time force and vibration data, and analyze the force and vibration laws. The existing test ...
