摘要：
To solve existing problems in environmental pollution and energy crisis for traditional transport modes, a new energy-saving and environment-protecting transport mode called the tube-contained raw material pipeline hydraulic transport technique was proposed. In order to further analyze vibrational migration hydraulic characteristics of a piped carriage in a horizontal straight pipeline, the software ANSYS Fluent 12.0 was used to do numerical simulation with fluid-structure interaction for structural responses of the piped carriage and the pipeline inside flow field. The flow field prediction was calculated with RNG k-ε turbulent model, while structure responses of the piped carriage were computed with structural dynamic equations. The results showed that the simulated values agree well with those of tests, and the relative errors are not larger than 4.8%; the instantaneous speed of the piped carriage in the horizontal straight pipeline reveals irregular vibration changes within a certain range, the vibration migration of the piped carriage can be regarded as a constant motion; the distribution of water head of pressure- measuring pipe in the area near wall of the piped carriage is W-shaped; the average energy loss of the piped carriage during migration is linearly related to the pipeline flow; the study results are valuable for further accurately grasping the transient variation characteristics of axial flow velocity and pressure during the vibrational migration of the piped carriage in a horizontal straight pipeline. © 2019, Editorial Office of Journal of Vibration and Shock.
