This paper aims to establish an electromechanical coupling dynamic model of HST traction transmission system and study its electromechanical coupling vibration characteristics, in which the internal excitation factors such as gear eccentricity, time-varying meshing stiffness, backlash, meshing error, and external excitation factors such as electromagnetic torque and running resistance are stressed. The research results indicate that gear eccentricity and running resistance have a significant impact on the stability of the system, and gear eccentricity leads to intensified system vibration and decreased anti-interference ability. In addition, the characteristic frequency of gear eccentricity can be extracted from mechanical signals and current signals as a preliminary basis for eccentricity detection, and electrical signals can also be used to monitor changes in train running resistance in real time. The results of this study provide some useful insights into designing dynamic performance parameters for HST transmission systems and monitoring train operational states.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"41 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679508","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}

This work utilizes molecular dynamics simulation to explore the hardening mechanisms of T-carbon thin films under nanoindentation with variations of loading velocities and temperatures. The results reveal that a loading velocity increase at a given temperature raises the nanoindentation force. The increase in nanoindentation force is due to graphitization, which is related to the fracture of tetrahedral structures in T-carbon thin films. However, increased graphitization caused by an increased temperature lowers the nanoindentation force at a given loading velocity. The increased graphitization is influenced by both the fractured tetrahedrons and the deformation of inter-tetrahedron bond angles. This is attributed to the loss of thermal stability and the lower density of T-carbon thin films as the temperature increases.

Most published nanofluid flow models assumed constant thermal conductivity and viscosity. With such great physiognomies in mind, the novelty of this work focuses on comparing the performance of the nanofluid models, Xue, and Yamada-Ota models on a stretched sheet with variable thickness under the influence of a magnetic field and quadratic thermal radiation. The altered boundary layer equations for momentum and temperature, subject to adequate boundary conditions, are numerically solved using an optimized, efficient, and extensive bvp-4c approach. The effects of non-dimensional constraints such as magnetic field, power index of velocity, wall thickness parameter, and quadratic radiation parameter on momentum and temperature profile in the boundary layer area are analyzed thoroughly and outcomes were illustrated graphically. Additionally, the consequences of certain distinctive parameters over engineering factors are also examined and results were presented in tabular form. From the outcomes, it is seen that fluid velocity slows down in the presence of a magnetic field but the opposite nature is observed in the case of temperature profile. With a higher index of velocity, the velocity profile decreases and the temperature field elevates. It has been found that the presence of quadratic convection improves the temperature field. The outcomes of the two models are compared.

Exploiting these effects and describing the axial material distribution by the Chebyshev expansions, the constrained particle swarm optimization algorithm is adopted to design two low-frequency vibration isolators, in order to demonstrate the feasibility of using functionally graded materials to isolate low-frequency vibration and maintain structural stiffness.

It is reported that large flexoelectric behaviors can be obtained at the nanoscale because of the size effect.

The flexoelectric-like effect is an enhanced electromechanical effect coupling the flexoelectricity and piezoelectricity. In this paper, a composite structure consisting of piezoelectric dielectric layers and a CS layer is proposed. The electromechanical response of the CS is significantly enhanced via antisymmetric piezoelectric polarization. Consequently, the cross-scale mechanically tuned carrier distribution in the semiconductor is realized. Meanwhile, the significant size dependence of the electromechanical fields in the semiconductor is demonstrated. The flexoelectronics suppression is found when the semiconductor thickness reaches a critical size (0.8 µm).

However, there is still a lack of understanding of the mechanisms that maintain a plasticity gradient to prevent the premature failure of fine grains in GS materials. In this work, by incorporating experimental data and the Hall-Petch relationship, we develop a size-dependent crystal plasticity model to investigate the deformation mechanisms for enhancing the strength and plasticity in polycrystalline high entropy alloys. The simulations of the GS model align well with the experimental results, exhibiting strong strain and stress gradients to improve the mechanical properties. Under the conditions of significant deformation incompatibility, the strain gradient predominantly drives the enhancement of plasticity mechanisms. As the deformation incompatibility decreases, the stress gradient begins to play a significant role in comparison with the strain gradient. This shift is attributed to the regular variations in dislocation density within different domains. As the grain size gradients and loads decrease, the dislocation density becomes more uniform across the domains, hindering the formation of strong domain boundaries. While this may impede the activation of strain gradients, it facilitates the activation of stress gradients as a supplementary measure. By designing multilayered GS structures to alter the distribution of dislocation density, we can control the activation levels of stress and strain gradients, thereby influencing the plasticity mechanisms and mechanical properties of the material.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7109,"journal":{"name":"Acta Mechanica Sinica","volume":"41 10","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889811","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}
