摘要：

Here, to make up for lack of test study on vortex-induced vibration (VIV) of multi-span pipeline at present, comprehensively considering fluid-solid-soil multi-physical field coupling, a complete set of towed tank test system was creatively designed to conduct test observation on VIV of multi-span pipeline. This test system could realize data acquisition about effects of submarine pipeline structure properties, soil body action, incoming velocity, pretension and other factors on VIV of multi-span pipeline, and provide data reference and verification for subsequent theoretical study and numerical simulation of VIV of multi-span pipeline. The results showed that the designed system can accurately simulate complex VIV phenomena of multi-span pipeline; the study results can provide a new idea for test study on inter-span action mechanism of multi-span pipeline, and provide test equipment support for systematic study on VIV of multi-span pipeline. © 2023 Chinese Vibration Engineering Society.
