A mesh insensitive finite element method to compute statical stability curve of floating bodies with arbitrary configurations based on a force-oriented approach

Zhengyi Zhang et al.

Summary: This article proposes a force-oriented approach, combined with a finite element procedure, to compute statical stability curves of floating bodies with complicated hull forms. The method meshes the hull surface with triangular elements and directly calculates the buoyant force and restoring moments. Results show that the approach is insensitive to the mesh pattern.

Theoretical and experimental study on the fluid-structure-acoustic coupling dynamics of a new water lubricated bearing

Zhongliang Xie et al.

Summary: This study presents a breakthrough in the performance of load increase, drag reduction, vibration decrease and noise containment through the design of a double-liner bearing structure. By constructing a fluid-structure-acoustic interaction hydrodynamic model and analyzing the lubrication performances considering cavitation effects and sound radiation, the study investigates the fluid-structure-acoustic characteristics and sound radiation laws with different material combinations, as well as the effects of operating conditions on deformation and stress. The results show a close relationship between acoustic performances and material combinations.

The fluid-structure interaction lubrication performances of a novel bearing: Experimental and numerical study

Zhongliang Xie et al.

Summary: This paper proposes a novel double-liner bearing to overcome the disadvantages of traditional water-lubricated single-liner bearings, aiming for breakthroughs in high-load, low-resistance, vibration attenuation, and noise reduction performances. By establishing a fluid-structure interaction dynamic model of the sandwich liner bearing and considering turbulent effects, the influences of eccentricity ratios and liner thickness on lubrication performance are studied, revealing the evolution mechanisms of liner thickness on lubrication performances. The results demonstrate superior lubrication behaviors in the sandwich liner bearing. This study enriches the theoretical systems of lubrication and provides new ideas and approaches for bearing design and R&D, which is of significant importance.

Experimental and numerical study on the mixed lubrication performances of a new bearing

Zhongliang Xie et al.

Summary: Traditional water-lubricated bearings face challenges in forming effective lubricating film under extreme low-speed and heavy-duty conditions, leading to shortcomings such as low-load, high-resistance, high-vibration, and high-noise. The paper proposes a novel multi-field coupling lubrication model to investigate the mixed lubrication performances and critical characteristics of these bearings. By developing functional mapping relationships and building rotor dynamic models, the paper reveals the variation mechanisms of dynamic behaviors and verifies the correctness of the model and algorithm through theoretical analysis and experiment. The academic value of this research is expected to achieve a novel breakthrough in forming effective hydrodynamic film under extreme severe conditions for water-lubricated bearings.

BEM-FEM coupling for the hydroelastic analysis of propeller-shafting systems in non-uniform flows

Jiasheng Li et al.

Summary: Understanding the hydroelastic behavior of the fluid-propeller-shafting system is crucial for reducing vibration and noise in underwater vehicles. A method combining a three-dimensional panel method with a three-dimensional finite element method for analyzing the hydroelastic dynamics of fully coupled propeller and shafting systems in non-uniform flows has been developed. The study finds that designers need to consider the elastic coupling effect between the shaft and propeller, especially with high-skew propellers. Additionally, the uncoupled model underestimates fluid-induced damping.
