Influence of Ocean Current Impact on Fluid-structure Coupled Vibration of Deep-sea Mining Equipment’s Hydraulic Pipelines
摘要
Abstract
The Bernoulli-beam model was employed to study the influence of ocean current impact on fluid-structure coupled vibration of the deep-sea mining equipment hydraulic pipeline. Through the dynamic analysis of the flexible pipe-line under internal fluid flow, the fluid-structure coupled vibration equations were established. The behavior of the hydraulic pipeline with and without external periodic impact was simulated respectively. The simulation results show that the external periodic impact can exacerbate the fluid pressure fluctuation in the pipeline and increase the maximum displacement of the hydraulic pipeline vibration.关键词
