Summary: The classical dimensional analysis method has limitations in determining the uniqueness and relative importance of dimensionless quantities. A machine-learning based approach is proposed to address these limitations, combining an artificial neural network with data-driven dimensional analysis. The effectiveness of the proposed method is validated through benchmark pipe flows and a fluid-structure interaction system, showing consistent results with those reported in the literature. The advantage of the proposed method lies in its ability to identify relatively important dimensionless quantities without relying on complex theoretical equations.

Summary: In this study, the implosion caused by the failure of the spherical pressure hull and interference with the adjacent cylindrical shell in a double-hulled submarine cabin was analyzed using the open-source finite element solver OpenRadioss. The implosions of the cylindrical tube and destruction of the spherical pressure hull were compared with experimental results, and the underwater implosion of the sphere was analyzed inside a cylinder with local impacts in different induced directions. The results showed that the flow field and structural deformation exhibited obvious directivity, and the deformation of the cylindrical shell was mainly caused by absorption rather than shock wave effect when implosions occurred in the direction closer to the cylinder. The dynamic responses of implosions were discussed under different triggering modes and hydrostatic pressures, revealing that the effect of triggering modes became more significant with increasing hydrostatic pressure.

Summary: This study proposes an anti-reflux biliary stent with a retractable bionic valve and investigates its mechanical performance through a 2D equivalent fluid-structure interaction (FSI) model. The design parameters of the stent are optimized using an orthogonal design, resulting in a structure with a high retrograde closing ratio. The finite element model confirms improved radial mechanical performance and flexibility for the optimized stent. Experimental measurements and FSI model results both validate the superior anti-reflux performance of the newly designed stent.

Summary: A mechanical model suitable for deepwater test string was proposed and the dynamic response of the test string under different frequencies, different water depths, and different fluctuation amplitudes was analyzed using the finite element method. The results showed that the response parameters tended to be stable after a certain period of fluctuation in the axial force and internal pressure. The amplitude, frequency, and period of the fluctuation had significant effects on the response parameters. The conclusions provide a basis for analyzing and preventing fatigue failure in test strings.

Summary: The transient hydrodynamic lubrication model of tilting pad journal bearings was established using computational fluid dynamics and a self-developed dynamic grid program. The study analyzed the dynamic response of TPJBs under various unbalance, loading modes, and rotating speeds, proving the feasibility of the model. The research found that different unbalance, loading modes, and rotating speeds can affect the whirl orbits, transient forces, and rotation angles of the pads in TPJBs.

Summary: A three-dimensional straight pipe-curve fluid theory and numerical approach based on finite elements are proposed for analyzing the vibration behavior of curved pipes conveying fluid. The methodology is tested on semicircular curved pipes, and the coupling vibration mechanisms between in-plane and out-of-plane systems are explored. The influence of nonlinear terms on the vibrations is discussed to simplify the theoretical model.

Summary: This study investigates the vibration response and damage detection method of fluid-filled thin cylindrical shells under the fluid-structure interaction condition. The vibration response is derived using high-order partial differential equations and the wave propagation method, while crack effects are studied using fracture mechanical principles to construct a local flexibility matrix and a breathing linear spring model. Results show significant variations in displacement response caused by nonlinear excitations, decrease in local flexibility and natural frequency due to cracks, and the effectiveness of normalized input power flows as a damage detection method for the shell.

Summary: In this work, the dynamic response and failure mechanism of urban bridges under far-field blast loads are numerically investigated. Approximate far-field blast waves are input into the air domain through the Autodyn subroutine to address the excessive model scale caused by direct simulation and remapping methods. The reliability of the loading method and fluid-structure interaction simulation scheme is demonstrated by published experimental data. The refined numerical model of the bridge is established based on an urban bridge prototype, and the failure process and damage modes of the bridge under far-field explosions are analyzed, along with the effects of impact angles and load parameters.
