Playing a critical role in transmitting movement and power, the meshing performance of spiral bevel gears has a significant effect on products' operational performance. To evaluate the meshing performance, the accurate three-dimensional(3D) spiral bevel gear models are established through the Pro/E and MATLAB softwares, and the finite element analysis(FEA) methods are applied to the theoretical investigation of the influence of cutter diameter on meshing performance in spiral bevel gears. The results obtained show that the cutter diameter has a significant influence on spiral bevel gears' meshing performance, such as the contact area, contact pressure, bending stress, torsional stiffness and transmission error.

Influence of Alignment Errors on Contact Pressure during Straight Bevel Gear Meshing Process

Chinese Journal of Mechanical Engineering 2015年第6期28卷 1089-1099页

Straight bevel gears are widely applied in automotive, aerospace, chemical and many other fields as one of the most common type of gears. Currently, the researches on straight bevel gears have focused on the fields of fatigue, wear, noise and vibration, while little attention is paid to the effect of multiple alignment errors on the gear tooth wear. To study the influence of alignment errors on the gear tooth wear, a simulated model of a straight bevel gear pair is established. Then, the contact pressure on the tooth surface is analyzed under the various alignment errors according to the Archard wear relationship. The main combinations of alignment errors played vital roles on the tooth wear are investigated. The result shows that under the single alignment error, the contact pressure moves to the tooth heel and increases greatly at here when ？P=0.1 or ？G=0.1; when ？E=–0.03, the contact pressure greatly increases at the tooth heel, but it obviously increases at the tooth toe when ？E=0.03; the alignment error ？γ=1 has little effect on the contact pressure on the tooth surface. Moreover, the combination of ？P, ？G, ？E〈0 and ？γ is the most dangerous type among the multiple alignment errors. This research provides valuable guidelines for predicting the tooth wear under various alignment errors.

Solar-driven interfacial evaporation (SIE) emerge as a promising technology to mitigate the worldwide freshwater shortage and energy crisis. Carbon nanotubes (CNTs) are widely used for the construction of hydrogel evaporators. Nevertheless, their evaporation performance is still restricted by their poor dispersibility and strong hydrophilicity. Even worse, the agglomeration of CNTs will diminish the formation of porous structures within the hydrogels and weaken the water transportation, finally resulting in decreased evaporation efficiency. To address those issues, CNTs with improved dispersibility and hydrophilicity are successfully achieved via metal-phenolic coordination chemistry-based interfacial engineering. The resulting metal-phenolic networks (MPN)-coated CNTs are further incorporated into a poly(vinyl alcohol) hydrogel, to synergistically realize superior photothermal performance and water molecule activation. In this way, a robust solar evaporator with hierarchical pores is fabricated for efficient evaporation and mass transportation, which achieves a rate of 2.9 kg m−2 h−1 under 1 sun illumination while maintaining stable operation in long-term and high-salt environments. Actual outdoor experiments and catalytic gel formation in acrylamide hydrogels further confirm the robustness of these MPN-coated CNT-based devices for SIE. It is believed that this study paves a new avenue toward the development of carbon-based hierarchically porous hydrogel evaporators, for efficient and stable solar evaporation. © 2025 Wiley-VCH GmbH.

Optimization of porous transport layer for overall performance improvement in unitized regenerative fuel cell under clamping pressures

引用

Renewable Energy 2025年 251卷

作者： Ke Chen Zhongzhuang Xiong Dandi He Zongkai Luo Guofu Zou Wenshang Chen Ben Chen Hubei Key Laboratory of Advanced Technology for Automotive Components Wuhan University of Technology Wuhan 430070 China Hubei Collaborative Innovation Center for Automotive Components Technology Wuhan 430070 China

The porous transport layer (PTL) in a Unitized Regenerative Fuel Cell (URFC) is essential for achieving high electrochemical performance and operational stability. It facilitates gas diffusion, regulates water-gas transport, and supports electrochemical reactions. Clamping pressure profoundly influences URFC performance by altering key properties such as porosity, permeability, electrical conductivity, and the contact resistance between the PTL and bipolar plate. Thus, the interplay between clamping pressure and the PTL is critical for optimizing URFC performance. This study focuses on investigating the effects of clamping pressure on URFC performance, uncovering key principles for optimizing PTL structural properties to enhance the overall performance of the URFC. Simulation results based on a two-dimensional finite element model and a three-dimensional two-phase electrochemical model reveal that clamping pressure induces asymmetric mechanical behavior in the PTL on either side of the URFC. As clamping pressure increases, significant changes occur in transport properties, which strongly affect mass transfer processes in the URFC. Furthermore, the study integrates Box-Behnken design, artificial neural networks, and the non-dominated sorting genetic algorithm-II method to develop a precise regression model for identifying optimal design solutions. Under the optimized configuration, the URFC's input power density and output power density increased by 4.08 % and 9.47 %, respectively, while the round-trip efficiency improved by 14.13 % compared to conventional configurations.

Towards reducing planar anisotropy in AZ91 magnesium alloy sheets with different loading modes: Experiment and simulation

引用

Materials Characterization 2025年 225卷

Uniform forming for high-performance magnesium alloy components puts forwards a requirement on magnesium alloy sheets with low planar anisotropy, and planar anisotropy can be effectively reduced by many severe plastic deformation technologies. In the present study, to clarify the effect of different loading modes on reducing planar anisotropy, initially-extruded AZ91 magnesium alloy sheets were subjected to single degree-of-freedom rolling and entire forging. Experimental investigation and modeling simulation were carried out to compare and analyze the planar anisotropy reduction with different loading modes in AZ91 magnesium alloy sheets. The initially-extruded AZ91 magnesium alloy sheet exhibits obviously different texture components with extra basal texture along initial extrusion direction and different proportion of prismatic and pyramid textures in different directions, and consequently evident planar anisotropy. After subjected to the two technologies, except for a little remaining basal texture along initial extrusion direction, there are only prismatic and pyramid texture in all directions both for the single degree-of-freedom and entire forged AZ91 magnesium alloy sheets. Compared with single degree-of-freedom rolled one, the entirely forged AZ91 magnesium alloy sheet exhibits much more similar proportion of prismatic and pyramid texture in all directions. Except for the strength of the single degree-of-freedom rolled one, both the two technologies can effectively reduce planar anisotropy of strength and plasticity in relative to initially-extruded one. The planar anisotropy reducing is mainly attributed to combined contribution of similar microstructure and texture through experimental observation plus similar strain-effective, stress-effective and metal flow through simulation in different directions. It is expected that this study will provide the optimal loading mode for reducing planar anisotropy in magnesium alloy sheets.
