RESEARCH ON SOLUTION METHOD OF CONTACT STIFFNESS OF CURVIC COUPLINGS CONSIDERING TOOTH SURFACE ROUGHNESS
Published 2020-01-01“…Aiming at the problem that the contact stiffness analysis method of curvic couplings can not consider the contact interface microscopic morphology,an analytical model of the contact interface stiffness was proposed.Through the stress analysis and stiffness transformation,the general model of curvic couplings contact interface stiffness was obtained,and the GW rough surface model was brought into it to obtain the specific curvic couplings contact interface stiffness formula based on the GW rough surface model.Finally,the analytical model results were compared with finite element results.The effect of surface topography on the contact stiffness of curvic couplings was obtained,and the relationship between the normal contact stiffness and the tangential contact stiffness with the preload and tangential force were obtained.The research shows that the analytical model matches well with the finite element results,which proves the rationality of the analytical model and provides a theoretical reference for the preload force and torque design of the rotors with curvic couplings.…”

Dynamic generation of superflow in a fermionic ring through phase imprinting
Published 2025-01-01“…In particular, we show that, as the interaction strength increases, the azimuthal density distribution becomes less susceptible to the phase imprinting potential, leading to a smaller quantized current under the same imprinting parameters. Our results offer microscopic insights into the dynamic development of superflow in the phase-imprinting process, and are helpful for the ongoing experimental effort.…”

Green 5G ultra-dense wireless heterogeneous networks:guidelines,techniques,and challenges
Published 2017-06-01“…Ultra-dense wireless heterogeneous network (Ud-HetNet) has been recognized as one of the most promising 5G network-organization techniques to significantly improve the wireless capacity and thus solve the 1 000× data challenge faced by cellular networks.However,counter to the expected 5G vision,although benefiting from the spectrum efficiency (SE) improvement,ultra-dense network deployment significantly increases system energy consumption and thus decreases network energy efficiency (EE).The key theories and techniques for energy-efficiently deploying Ud-HetNet were investigated from two aspects of macroscopic network matching and microscopic resource aggregation by exploiting their overall network management capabilities and network diversity effects.Specifically,the overall design guidelines for green evolution were introduced firstly,and then three techniques,namely load-aware base station on/off switching,proactive caching,and interference-aware cross-network resource allocation,were proposed to improve the network EE.Open issues and challenges that need to be further explored were also discussed.…”
