The general dynamic model of a damped gas turbine shaft is simplified by converting it to an equivalent undamped gas turbine shaft using the dual estimate. Two globally optimal expressions for the parameters of the MDVA system are suggested based on rigorous mathematical evidence to weaken the torsional oscillations of a damped gas turbine shaft. Numerical simulation results have verified that the globally optimal expressions of the MDVA system suggested in this study generated surprising results for weakening the torsional oscillations of the damped gas turbine shaft. In addition, the results of investigating the influence of the installation location and number of single dynamic vibration absorbers (SDVAs) of the MDVA system have shown that the torsional oscillations weakening effect of the MDVA system enhances corresponding to increases correspondingly with the increase in the number of SDVAs and the farther the installation location of the MDVA system is from the center of the gas turbine shaft.

Although the PINNs have been successfully applied to many branches of applied mathematics in recent years, their effectiveness and accuracy still require further improvement. Beyond the network architecture and learning algorithm, the preprocessing of data has been identified as a critical factor for PINNs performance. This study systematically compares PINNs preprocessing methods, with particular focus on three universal approaches (the non-dimensionalization, inner normalization layers, and synergistic normalization method for data and equation). We evaluate these approaches through ten benchmark fluid mechanics cases governed by fundamental PDEs types: elliptic, parabolic, hyperbolic, and mixed-type, covering forward and inverse problems. The results of the test cases show that adding normalization operations in PINNs significantly improves performance, which enhances training stability. However, their effectiveness varies substantially depending on the type of governing PDEs. For hyperbolic and mixed-type equations, which often exhibit ill-conditioned loss landscapes, the synergistic normalization method outperforms the alternatives notably. In contrast, for elliptic and parabolic problems with a well-conditioned loss, the SynerNorm method may be less effective than the inner normalization layer method. This study provides a practical reference for selecting preprocessing methods in different physical scenarios.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"42 11","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148380128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the boundary element method is employed to investigate the dynamics of bubbles under the influence of pipe flow. The accuracy of the numerical model is validated through comparisons with theoretical predictions and experimental results. Based on this, a systematic analysis is conducted to examine the effects of initial internal pressure, flow velocity, and pipe dimensions on bubble motion and collapse behavior. The study shows that bubble motion in a pipeline is influenced by multiple factors. Higher initial pressure increases the bubble’s energy, leading to a larger maximum radius and higher wall pressure during collapse. Increased flow velocity causes asymmetric bubble collapse, making the jet more likely to impact the pipe wall and enhancing post-collapse offset effects, while also affecting the bubble oscillation period. A larger pipe radius weakens wall confinement, reduces peak jet loads, but prolongs the oscillation period and influences energy distribution.

The work proposes an electromechanical coupling polygonal hybrid element model, where the stress field and electric displacement field are independently assumed within the element domain, while displacement and potential are independently assumed on the element edges. By introducing displacement and potential as Lagrange multipliers into the complementary energy functional, the generalized surface force equilibrium conditions at element boundaries are relaxed, thereby establishing a modified complementary energy functional. Consequently, a four-variable function involving stress, electric displacement, displacement, and potential is proposed. The stress and electric displacement in the domain satisfy the equilibrium equations a priori, thereby constructing higher-order stress and electric displacement functions. Displacement and potential are interpolated exclusively on the element boundaries. The proposed hybrid element eliminates shape function requirements and applies to arbitrary polygonal elements, enabling the combination of polygonal-quadtree meshes. The accuracy of the polygonal-quadtree mesh element is validated through comparisons with pure quadtree mesh elements.

To clarify the underlying loading mechanisms and guide test design, this study establishes a coupled electromagnetic-mechanical theoretical framework together with a simplified formulation for insulating specimens.

However, the IPMCs-based actuators in practice are often subjected to an electrochemical-mechanical coupling cyclic loading, which can lead to performance degradation or failure. Long-term actuation is primarily influenced by two key factors: (1) weakening of counterion migration due to internal electrode cracks, and (2) migration weakening of water molecules due to waterloss. Notably, these dynamic transfer-dependent fatigue behaviors are significantly greater than static damage-dependent fatigue behavior from polymer chain fracture and electrode metal damage. These electrochemical-mechanical coupling properties and dynamic transfer-dependent fatigue characteristics of IPMCs complicate the accurate prediction of their long-term actuation behavior and fatigue life. This study develops a double species diffusion-dependent fatigue to systematically and quantitatively characterize the IPMCs’ long-term performance. The model incorporates cross-diffusion and time-dependent migration, weakening of counterions and water molecules. Micromechanism-based electrochemical-mechanical constitutive and loss relations are derived using Langevin statistics and the Eyring equation. Building on this foundation, an electrochemical-mechanical fatigue damage index is introduced to quantify the relationship between the driving force weakening, cycle period, and fatigue life. The finite element implementation is realized, and the simulation model is calibrated through a series of tests. The long-term actuation behavior and dynamic transfer-dependent fatigue characteristics of IPMCs under cyclic electric excitation are analyzed, and the fatigue life is predicted under varying initial water concentrations and electric field intensities. Results show that fatigue life decreases with increased electrical stimulation and lower initial water concentration.
